Heat Problems with abit IS7 and P4 3ghz

[VitoVonAntwon]

Hello,

I Just put together a p4 2.8c (o/c to 3 ghz), with Hyperx 512 3500 Ram.
Got a Antec Truepower 430w, which has the silent fan, and controls 2 fans that run slower
but quieter. The machine runs about (2.8/3.0) 50-54 at Idle, and 65-69 at load. IS that hot, I think it's a bit high but not outragous. System Temp is 45c

I'm going to get some more fans, and the whole thing is in an Antec plusview1000.

ANybody know anything about negative pressure and whats the best way to set up your fans. Like 2 fans in the front sucking air in, 2 fans in the back blowing air out, and one side sucking in air, and the psu blowing out air. (So all the air is sucked in from the front and side?

I am waiting for my fans, need a place to order them, Saw a place for panaflow since they are so quiet, i'm really into that.

Whoa! that is super hot in my book... I'm in LA and the temp in my house is about 30 degrees C or about 87 degrees F - I'm sweating my balls off here cause its so hot! my temps inside my system are 41 C system and no more than 50 C load for the CPU. Plus I'm still using stock cooling, overclocking my 2.4c to 2.6ghz (too hot to go up in my opinion). What you need is watercooling (all I need is my BIX radiator and I'm set to oc to 3ghz+).

About fan pressure... generally speaking you want- in = out. Most people have 2 out fans in the rear and 1 in fan at the front. This creates negative pressure on the inside. Still, if your house is hot as hell like mine, fans aren't going to help you. Especially at that temp. My advice is if you can't afford a watercooling setup ... then get a big fan and leave your case open.

You have the identical setup that I do. The Abit IS7 has a documented problem where some of them report higher than actual temps. Check out the IS7 thread over in the motherboard section to read other people having the same problems.

However, it *is* possible that you may have cooling problems. Leave the case open (preferably with a box fan blowing into it) while you test things to eliminate case airflow as a problem. If you applied thermal compound to your heatsink, you may want to double check to be sure you put a thin, even coat on it. Assuming your heatsink is attached properly, then you most likely have the inaccurate temp problem. It is usually off anywhere from 6 to 12 degrees C which could mean your processor is actually running 40 to 55 C. My IS7 reports my temps as 39 to 55 C. I think I was lucky and got one that didn't have as large of a temp. reading problems that some of the others do.

Anyhow, just be certain that you're heatsink is properly connected.

Thanks. I used artic silver III, Zalman seems screwed on right.
I"m going to take it off, clean it all up, try the stock cooler that came with it.
See how that does. Then I'll try again. I think I did it correctly though.
Definately need more those 3 more case fans and the rheostat. I'm not sure how much more of a help they will be, as you said. Very big swing, of 20degrees between load and idle. Abit site reports that's normal. I'm not so sure. After about 20 minutes of running lightwave benchmark,
WHere the cpu gets up to at times 68c, machine would restart. Hoping this is only a heat problem, becasue I plan on leaveing this thing rendering all week. Crossing fingers.

I too have heard the temp problem with that board, but if it is correct. 65degrees is already to hot. I have mentioned on threads before, but FYI 67degrees Celcius (real temperature) is when P4 northwoods start throttling down. In my oppinion it would be wise to stay out of 60degree plus temperatures completely just to be safe. In my practice, I try not to exceed 55degrees just in my experience...

Thanks for the tips. I pulled out one of the Kingston 512 Ram chips, and it stopped crashing after the 30 min mark.
It's been at 100% cpu, and rendered out 30 frames of the raytrace benchmark. Before it would get to about 15-20, or so frames.
Each frame is about 1.4 min long. So now at 30 frames, it's still chugging along as I write. Hyperthreading does one thing, it allows the machine to still be responsive while rendering, never could do that before. (To a degree.)

SO OPened the case, but no extra fans, and the since I took the ram out, the Temp dropped to 65, From about 68, 69 before.
I'm going to just let it render benchmarks all day on one ram chip, and all day tomorrow on the other chip. Then I'll try em again together.
I'm not sure if it's having problems with double data rates, but When I had both chips in it didn't seem to affect the benchmark readings at all.

I'm going out to find some alchohol with 70% or better readings. Had some in stock, but it was only 50%. (concerns over residue.. Does it matter?)

I'll post some temp numbers later, as I swap out the zalman. I should have tried the stock cooler first.

ALso the Hyperx 3500 ram is at timing 2-7-3-3. But std varyies every time i boot and check. Wierd. some times its says it's a 2.5cas 2-8-3-3, sometimes it's 2.0 cas 2-7-3-3, so wondering whats the problem. I"m wondering if it takes an average of the 2 chips in double data mode? SOme one mentioned that when you got 2 in, the spec changes.

So far been on for 2 hours with no crashes at 100% cpu load, with 2 instances of lightwave running benchmarks, WIth only one 512mb Chip in.

Can't seem to get it to even post with anything higher than 3.0 ghz. Any ideas how to get it to 3.2ghz? I think the fsb was 215, Isn't this ram rated at 234?

Question, I put on a rice sized amount of artic silver, and spread it around the cpu with my finger inside a bag. It looked like an even and thin coating.


Do you think that if you put to much you would increase tempretures?

Putting too much thermal paste is always bad. You just want to fill the micro cracks of the mediums, not create the medium for heat transfer itself. Even polishing the surfaces of the heatsink or processor(assuming you are dealing with P4 for those reading), enhances the effect of heat transfer... Just make sure you have an even amount across the chip. Over time the paste should make it's way to where it needs to be, which also brings up that you shouldnt go and dive into overclocking right away. Even Artic-Silver says that you need to cure the product for "72 hours" before the product will work at it's optimum... And on the ram thing, I would relax the timings a bit or pull the mem voltage up to 2.65volts at least. Most good memory like you got there, don't even void your warranty until more than 2.7volts. I run my Corsair XMS3200 at 2.7v all the time for best results...

Thanks.

When you mean relaxed, can you give an example? Voltage for ram, bumped up to 2.7 and that worked miracles.
Couldn't even get the 2.8c to work at stock speed with the mem voltage lower. Go figure.
Changed the timings of ram to 2.0c 2-7-3-3 and Changed the fsb to 234. Which worked stable no problems.
I was trying to set the thing to 1:1 and fixed timing for everything else, would not even post.
But Changing the the agp settings to auto, now this thing seems pretty stable at 3.28ghz. The funny thing, is no change in heat.
GOing to keep on pushing it. See how far this p4 2.8c from costa rica will go.
Running Lightwave benchmarks again. So far 1.5 hours no problems. Lightwave Crashed once. But it didn't take down the system.
Started up again, Hopefully, will be able to go all 60 frames, once again about 1.5 minutes each frame. WIth open case heat is about 67.

I wish I knew how people are getting 55c with load? I have a Zalman. I will have to clean up the cpu and try it again.
I will also see how the stock cooler works.
