I had a B3 and had to RMA because of separate issue, but received the new one and it was a G0!! Installed it with AS5 on my Zalman 9500 and the temps idle are in the mid 40s (44-47 between the cores). I've read in SO many places that it should idle in the low to mid 30s. I have another thread on this issue here, but I'd like a fresh set of eyes on this situation because there seems to be some arguing over at eggxpert on my problem. WoodButcher (username on eggxpert) recommended this forum for more insight on the temp problem and I'd possibly like to get into Water Cooling. Need to save some $$ first for that, but that gives me some time for some research on parts and technology as I've no knowledge of WCing. I've seen the thread at the beginning of this forum, so I'll read that, and I hear that Aigomorla is quite the WCing guru here. Hope to learn a lot here!!

Thanks all for knowledge, in advance.:thumbsup:

well off my first guess, its your sink.

I cant stress enough to tell people that zalmans suck on quadcores.

But if your heart is in WCing. We need to know your budget, and modding experience.

Thats a great case, and has great potential if your willing to do some work on it.

Also would like to know what parts you would like to watercool. And if your going for pure performance, or if your going for silence.

When cooling somethiing with air, ambient temperatures are very, very important. Before I went to watercooling, I was having a hell of time getting my temperatures under control. I research for hours, read the Intel specification guides as well as basic cooling concepts. So, what I determined was that an idle temperature of 40-45c is actually quite common, especially if your case doesn't have the best air flow. If your case temperature is, say 38c and that is the air that is blowing on the heatsink, then you could only hope to cool the CPU casing (Tcase) to 38c, then add another 10c for the core temperature delta and you have an idle temperature of 48c. Reduce case temperature, have a duct from the side of your case that allows room temperature to be sucked in and blowed at the heatsink, which will reduce temps.

Just keep in mind the basic princable is that you cannot cool something cooler than the ambient temperature, unless you are using TEC or some other exotic form of cooling. Even water cooling performance is dependent on the ambient temperatures.

So, there are a few things you can try, in my opinion.

1) Remove side panel from case and check temperatures under idle and load, then put the case back on and redo the test... If you have more than a 3-5c delta, you need better case flow.

2) Remove the heatsink and verify that AS5 was touching the entire IHS. If it is, thne verify that it isn't too thick... It is easy to put too much of that on. Often, I would remove the heatsink, find a ton of it on, would then clean the heatsink only, then just install it again and temperatures lowered a little bit.

3) Lower room temperature... The higher the room temperature, the higher the case temperature and therefore, the higher the CPU temperature. The same computer in a 33c room will result in a minum of 10c higher CPU temps than when in a 23c room.

4) Go water. Even though water still is ruled by ambients, it is much less so because it can move the heat away much faster. Idle temps are not much better with water, but they are far, far better with load temperature, and that is the real problem. Running at 45c wouldn't be a big deal if load never peaked past 60c. But the reason 45c is a big deal is because you will see 75c+ under load, typically... Maybe even higher!

Water cooling does cost more, but it allows so much more headroom. It is generally more quiet and is incredable for load temperature.

So, do Zalman's suck for Quads in general, or will it work fine if I lap it?

As for WCing, I printed out your Newbie's guide. I'll have to read it more in depth later tonight, as I'm at work now. I'd like to spend right around $250 on parts, not much modding experience if you're referring to WCing. I've built my own PC from scratch and a couple others from scratch as well.

The case was a graduation gift that I got last weekend. I walked last Fri. for my AS in Computer Networking. I love the case!! I had the Apevia X-Cruiser before that, which I wasn't happy with. I am not too concerned with silence, more performance concerned. I originally thought that I'd just cool the CPU, but I'm not totally informed on the benefits of cooling the GPU. (Still have to read your guide :) ). I wasn't planning on OCing the Video Card, but I am open to it. Mainly, from what I've read thus far, I'd want to WC the CPU, and possibly the GPU.

Stupid Q: What is OP? I've seen it in threads and don't know what the acronym is.

Thanks Wood, for the suggestion of this forum, and thanks, aigomorla, for helping newbs to WCing like me!!

Lapping the chip and heatsink dropped 7-10 °C off my B3's load temps.... what are you load temps by the way? Also what is your vcore? Have you tried minimizing it? These and more suggestions are in my overclocking guide. You can find the two links to my posts about lapping chips and heatsinks within as well. I'd say your first stop is to attempt to minimize the vcore. Also, please post your prime95 load temps (prime95 is linked in that thread).

Zalmans suck in general for quadcores. I havent found many people who had multi sink options that would say zalmans were the best. When i say multi sink, i say people who have gone though many different sinks on the same platform.

The consensus and also tests from many different people, Tuniq Tower, or Thermalright Ultra120 Extreme is the best solution for your quadcore on air. The thermalright will require lapping however. But remember archangel's post. Your internal ambients will play a big role in temps.

but back to your original problem, i forgot you have a G80 in there. Arch Angel is absolutely correct in his statement. Im guessing its also your ambients. That G80 will put out a lot of heat into your case. Try poping the side pannel out for now, and see if that fixes your temps a bit. If it does, then maybe we can fix your issue with a few fans that cost 4-5 dollars each vs. a water migration unless you want to try it and really have your heart set on it.


OP = Original Poster. Meaning the person who made this thread.

Zalman heatsinks suck in general not just for quad cores. Their price/performance ratio is soooooo low.

You are much better off with a Thermalright U120 or a Tuniq Tower. Heck I'd even take a Thermalcrap heatsink over a zalman.

For water cooling, well there is no need for additional advice here, there is already plenty in the room.

Thanks for the responses guys, I knew you'd come through.
@ the "OP" - Many things I didn't think of here, I'm sure there will be more. Many, many qualified folks on this site.

edit-terencek, note how many quads are in the signatures! Every response you've gotten so far is from a quad owner,,,,,

I checked last night. The vcore is 1.275v, but that's on Auto. I have it stable at 2.799GHz the idle temps are at 44-48C. Load temps are at 61-64C. I know the max temp set by Intel is 70C, but obviously, I'd like to get as low as possible. I'll run Prime today, while I go to the USF Bulls game, and I'll post results later tonight. (Previous temps were taken 4-5 days ago.)

On another note, I can testify to the fact that ambient temps affect CPU temps. Last night we had a cold front move in (I live in Tampa Bay Area, FL, so it's typically hot) and the temps dropped 3C on avg. just because of the weather.

Now, aigomorla, what is the G80? I have a 680 mobo, is that what you are referring to? At this point, I'd like to solve this with air if I could, but down the road (After some research and saving $$) I'd like to go to water.

Thanks for telling me the acronym OP, I hate reading stuff and not knowing what people are talking about.:thumbsup:

I see people have 3, 4 and 5 jobs running in Prime95 all at the same time. How did they get that many jobs running? Do I have a version that doesn't do that? I just googled Prime and downloaded it. Just wondering if that'll stress it better, or if my Torture test works just fine.

Thanks again to all for their advice.

The "G80" Aigo refers to is your vid card.

You need not run test for extended periods of time at this point, your not testing for stability in fact I would recommend against it untill your temps are a little lower.
Have you run w/ your case open and checked the temp yet? as AA777 suggested airflow in your case could be a contributing factor. Where is your case? does it have room to breath?

I know very little about zalmans, I haven't used them but was under the impression that they were a quality heatsink. Did you run this chip with the stock cooler and was there a difference between the "Z" and stock?

Have you checked the chip for flat? I'm still thinking you need to lap but to exhaust all the other possibilities first is a good idea.

edit- I just looked at your case COOLER MASTER COSMOS 1000 ?,,,, that thing begs for internal water! My loop would fit w/ ease

OK, I didn't get this message til after I'd run Prime for 9 hours. I looked at the Core Temp log and exported it to Excel to find out that the avg. for the cores were 53-56C, the max on Core 1 was 67, but the others' max were 60-61C. I haven't been home to check if the chip is flat. I'll do that after I post this. As for open case, that dropped the temp 2-3C. The case is sitting next to my computer desk in my bedroom. It's not closterphobic, but it isn't in wide open spaces. That may be a factor.

The Zalman, I thought was a very good HS, from what I read on Newegg, but now I definitely know that I need to read in more places than 1. That's the only reason I bought it; lack of research on my part. LOL. I've never used the stock HS, I was told that they are crap, so I never bothered.

Yeah, this case seems very good for water cooling. I first saw this case as the Dream Machine '07 in Maximum PC. It looked like it had a great setup for water in that machine! The more I read, the more I want to do water, just need to save $$ and find the right parts. I don't want to make the same mistake as I did with the HS. I'd like to go for performance on the WCing, noise isn't too bothersome, as long as it's not like a jet plane next to my desk.

I'll post back with results of lapping the HS and checking the IHS. I bought all of the sandpaper today, and I have all of the other stuff.

well keep me updated with your progress.

When your ready to start buying blocks and stuff, drop me a pm. I'll point you to all the great stores, and recomend you some nice items which should fit your budget and get your objective down.

But just make sure you've taken care of any looose ends.

The last thing i would want you you to go though is, DOE i could just fixed my temps by doing solution X and not migrated to water.

So I got the HS and the IHS lapped and installed everything and the temps went down to 36-39C avg. between all the cores. I have it to set 2.9GHz right now. My end goal is 3.0GHz. If I can get it to that stable and not too hot, I'd be good.

I think that I'll still go with water cooling, but it'll be about a month til I can get that $$ together for that. Would it be safe to say that I can get a pretty good setup for $250-$300? I just want to cool the CPU and possibly the GPU.

Is there a thread on the benefits of WCing the GPU and/or how to OC a GPU? I haven't ventured into that area yet.

watercooling the gpu will not give you better overclocks.

The reason is because you cant really volt mod a videocard unless you do a hardmod and not a softmod.

Hard Mod would be using a conductive pen on the card, or sodering a wire and resistor.

Softmod is something done via software. Not many videocards allow for this.



The benfits of watercooling a videocard would be silencer, and longivity for the card. Most Max OC's can be hit by using an aftermarket air cooler however.

The CPU is another case tho.

about 300-325 is a good number to grab for both gpu and cpu.

Thanks again for everyone's help.

Was the IHS real bad on your quad? or were they both funky? I thought zalman was good w/ their finishing on the sinks. My E6600 was bad concave, I started lapping w/ 220 grit wet-dry paper and didn't move up till I got close to having all the nickel removed. It wouldn't surprise me to find the edges are almost sanded through for it was a good 1/32" concave. Your results are great, I'm happy it worked for you.
When you migrate to water post another thread and you'll get lot's of help and don't forget to PM Aigo- he's real sensitive, ;) You can be assured he has the current info on water, shh, don't tell anyone, I think he sleeps w/ a block under his pillow,,,,,, shhh! It's a secret!
As for bringing you to anan, your welcome, I find the newegg site to be funny, some of the eggxperts are really clueless though, I try to help where I can but when a mod starts trashing your thread it's best to leave.

:thumbsup:thanks again to all those that came to the aid of the new guy!

And yes i keep bugging him about it on XS forum. :p here's hopeing he gives in.

Well, I think this'll be the end of this thread, but here's where I'm at now. In Florida, we FINALLY got a good cold front to come through, so I've been leaving the windows open, and the temps in my case have dropped more. As suggested, I've been leaving the side of my case open for more airflow, which has helped a lot. I have a stable 3.1GHz OC - vCore is at 1.200v I believe. I've been lowering it, stressing, and lowering it over the past couple days. Idle temps (with these cold temps and side of case off) top out at 40-41C. I notice that Core 0 is ALWAYS 5 or so degrees higher than the others (that's the 40-41), the other cores are mid to upper 30s, but that's OC'd to 3.1GHz, so not too bad.

Now, I am just playing games (Call of Duty 4 ROCKS, can't wait til Crysis!!!) and reading up on WCing, and yes Wood, I'll be getting with Aigo when it's time to get the setup together. I think I'm set on just WCing the CPU, but have to read up some more.

I know I keep saying this, but it's hard to find good advice and I want you guys to know that I appreciate it, so :D Thanks to everyone for all of the help!! :thumbsup:

One thing to note - It is perfectly normal for one core to be 5c hotter at idle. Though the term idle is used loosely in that scenario. The reason that core is hotter (generally) is because it is the core that is taking care of all your backround tests. Even though you are sitting in windows doing nothing, XP, Vista is always doing things in the background, no to mention any other application (virus scanner?) and so on. Once you hit them at load though, you should see them even out. But, in any case, a 5c delta between all 4 cores is acceptable, just not exactily desireable.

Hey, guys!

Terencek -- Woodbutcher gave me a heads-up to post here -- suggesting I might have something to offer.

I'm stunned that you can't get the idle temperature for a G0 quad-core below what you've shown. I wasn't able to read through all the other posts here -- I'm "keeping busy" -- but I took a look at the Cosmos case.

I don't think the Zalman 9500 stood up too well in the May 2007 Anandtech comparison review focusing on the ThermalRight Ultra-120-Extreme, and later -- with the Ultima 90 review. But your temperatures should still be well below what you've shown.

When I first saw the Cosmos several months ago, I thought it was promising, but I took a closer look.

It's just my opinion, but I see one rear exhaust fan 120mm and two top fans (which could only be exhaust, I would think, the way they shipped that case.) That leaves only a single intake fan at the bottom.

There are myriad opinions about this, but I stand firm from a few years of case-modding and air-cooling experience: my recommended strategy is to overwhelm the case interior with exhaust CFMs and pressure, seal the rest of the case, duct the air over the hot components and force it out through one or more exhaust fans. This case doesn't do that.

I'm still running a B3 Q6600. I've got it OC'd to 3.204 Ghz at the 9 multiplier and a Vcore of 1.4125V. The TCASE temperature at today's current room ambient of 70F is about 25C, and my idle TJUNCTION Core temperatures are 37,36,40,46 (Everest seems to load up Core#0 (46C) with all its sensor reading for the fans, voltages, temperatures, etc.)

I still have some ducting refinements to my case, and I've added a second intake fan BEHIND my hard disks -- that lowered my RAID5 disk temperatures by another 5C across the board.

You could keep the Zalman, but you could do better with this. IC Diamond thermal paste is $5 -- that's worth about 2C or so. You can lap your processor and heatsink base. Using ducts in that case wouldn't be terribly complicated, but I'd like to see more intake air coming into it -- a lot more.

If you don't want to mod that case, at least to figure out how to add one extra intake fan -- maybe even block off and remove the top fans -- you really might want to consider water-cooling.

On the UP side, if you can keep your core temperatures below 70C at load, the G0 is still immensely over-clockable. You have to decide what you're going to do with that case.

For instance, I've taken to adding bottom intake fans (I know you have ONE there already), and using double-wheeled casters to lift the case off the floor for air intake. An extra fan on the bottom might do it. But I just think the Cosmos has too many exhaust fans -- unless I'm mistaken and the top fans are really intake fans.

Thanks Duck, terencek, before you migrate to water there are a few things you can do. Mods of minimal or no cost but elbow grease and time, When you came here I sent a few PMs' to those folks I found helpful to me in the past, and all I believe lap their chips, thanks again guys, well, I think Duck may be overworked because it took him awhile but the timing could not have been better.
Read his threads on ducting and experiment. I agree, additional venting or fans for intake would be helpful, If you could duct one 120mm fan directly to your cpu fan that would be ideal. Temporary ducts can be made from cardboard and scotch tape and then use the cardboard (if the results are good) for patterns on acrylics to make permanent. Cutting the case bottom is a great way to go but there are alternatives, here is one option. Now thatyou know your heatsink application is as good as it can be you need to find ways to feed it, cool air.
