T-Bird 800 mhz Way to hot! 130 F. Tried everything. Help

[Seizure]

Here's the specs on the system

Generic Mid Tower ATX case
AMD Thunderbird 800 mhz (Not overclocked)
20 GIG 7200 RPM Maxtor
Geforce2mx
Asus A7V
Alpha Pal 6035
Sunon 80 MM. 42 CFM
Regular Silicon Grease (Applied a little more than a thin layer.)
PCI Slot Cooler

Ok. With the case closed, The CPU will go up to 130 F, Mobo will be around 100 F
When I take the case off, and aim a regular human Fan at the cpu I can reduce the CPU temp down to about 115-120 F and lower the mobo down to 90F. But I don't want to leave my case open and aim the fan at my PC forever.

I've been reading everywhere that a regular average T-Bird CPU temp should be around 100 Degrees. What is the real average Temps for AMD T-Birds? What am I doing wrong? I have all the "better" cooling devices and my PC isn't even overclocked. I was thinking about adding Artic Silver as my Thermal greese, perhaps that can reduce my temp a bit.

What's your opinion guys?

Forgot to add that it has a 300W power supply and the slot cooler is located under the GeForce2 Card. And yes there is an Intake, 8 Tiny little holes in front.

 

[Ladies Man]

it's fine
130 is within the specs of what it should run at.
as long as it isn't locking up on you it's fine
130F is perfectly safe

The big drop in the temp when you blow your fan into your case might be b/c you are blowing air into the temp sensor, not actually from cooling your CPU itself.

Some of us speak only C in here, so next time please post both Fahrenheit and C.

 

[toph99]

maybe you have too much/little thermal compound? and i have no idea what 130F is in C, so i don't know if it's too hot or not

My T-bird 800 is currently at 54C which is 129F (according to VIA Hardware monitor). My system just freezes afer an two hours or more and I know that my temp has gotten up to 57C or so.

Do you think the temp. could be the problem? I've got a DP5 5H53-01 CoolerMaster that came with my mobo/CPU bundle from Mwave.com. On the CoolerMaster web-site, it is supposed to cool up to 1 GHz. I just put it on as it was--thermal tape, no grease.

What do you think? Should I try to get it cooler? I don't plan on O/C'ing. If you suggest grease, is it really that much more effective? And where do you put the grease? Just in the middle where the tape was? Thanks!

Lose the thermal tape, use grease instead. That will drop you several degrees. If that doesn't help, check out www.2cooltek.com or www.millisec.com for some larger heatsinks like an alpha or global win.

Good Luck!

I don't know why your T-bird is running so hot. As a reference, my t-bird @ 800 (not oc'd) is running at 89F to 90F (31.6C - 32.2C) under a full load (running SETI ). When I overclock it to 904, 113x8, it runs at 95F (35C) under a full load. Other than replacing the thermal pad with some good silver paste, the only other thing I can think of is that your case isn't providing enough airflow. You may also want to check to see if your running your CPU at the proper voltage, 1.7v for the core.

Just because you have been reading about them running at 100F does not mean that is accurate. Too many variables go into Socket A cpu temp measurement to accureately compare temps.

Among those variables:

MB
Thermistor Placement underneath the socket(yes, this is important)
Bios REVISION(also huge, as later Asus/Abit Bios' attempt to compensate for problems with thermistor temp measurement).
Heatsink CLIP Pressure(if you bought a PAL6035, but it wasn't a socket A Clip). Socket A cpu's require much more clip pressure than a p3 compliant clip.

Now, with the heatsink/setup you have, Your CPU should be about 16C over ambient at best(look to keep it around 16-20C over ambient and you'll be okay).

So I would first figure out which bios revision you have, then check to see whether you got the socket A compliant clip with the alpha. And I would look to increase case airflow, as your MB temp is pretty high.

Very informative Mikewarrior, I do have the socket A Complaint Alpha Pal heatsink. How do I check the BIOS version? I'm fairly sure my CPU voltage is correct since I didn't mess around with it. I definately think the generic case that's causing me the problem. Not enough Air Flow I'm assuming. However even if I leave the case open the Temp only drops a few Degrees Farenheit. So right now I"m just leaving it open and aiming a Human Fan at it and keeping the temp at a nice 100 F. I'm going to apply some Artic Silver perhaps that will help. So what's the best way to remove the current silicone grease I have on my CPU and Heatsink?

 

[Mikewarrior2]

Well, when you leave the case open, with no fan, does the temp drop?

Does the temp drop if you put a big fan(say 20 inch box fan) next to it?

Hey MikeW,

I have a question for you.

I am overclocking now around 1000 on my 800 with a CoolMaster HSF. ( I plan on buying an Alpha when they become available again. )

When I peg my system using SETI, my temps shoot up to around 58 C and my system will blue screens, freezers, or reboots after about 10 minutes. My idle temp is around 35 C, sometimes more.

Is my this due to the temp, which I assume at this point?

I also had a reboot when playing NFS3. My CPU temp was around 58 C at that point too.

I am just not sure if I have any other problems besides CPU temp...ie general overclocking??

Input is appreciated.

Yea. the Temp does drop when I put a Big 20 Inch fan next to it. The CPU drops to about 104 F which is about 38 C.

 

[Mikewarrior2]

Okay, Well, in that case, you may choose to leave your case open, but still do add some case fans to it to move the air around.


Strike,

I would hesitate to guess that your cpu isn't quite stable at 1ghz yet. Are you using hte PCTC pad that came wtih your coolermaster heatsink? Is the chip stable if you drop the speed to 950?

Mike

Thanks for the reply..

I dropped my settings down to 945 and all is stable. Temps around 54, maybe a bit more..

I was able to go up around 980 and the temps were still a bit too high, in my opinion.

Here is another thing I was concerned about....atleast pointing to the piece of crap CoolMaster. My case temp stays around 29 which is 25 less than my chip.... and I realize these temps are not necessarily accurate.

and, Yes I am just using the metallic pad under the heatsink. No grease at this time, I had applied some really old white grease I had, but didn't seem to help... But, I also wasn't sure if I should remove the pad first or just apply the grease and leave the pad on. When I tried it, I did NOT remove the pad... mistake?

Does anyone sell AS in tiny tubes? I don't need a 40 application tube, just 2-5. See opportunity for someone to sell tiny squirts to us who only need 1 application..

I had the same prob with a C'ORB on the same board. Unfortunatly i broke one of the stupid plastic nubs taking it off and had to use a generic heatsink now. I had it installed at a comp shop (they were nice guys, they've seen the same thing a couple times) and now it actually runs warmer and hits like 50 C but it's stable. I'm not worrying about it cause they had installed 100s of these fans and heatsinks on other thunderbirds for months and none have came back burnt out. should be fine. You got more case cooling than i do anyways.

 

[Mikewarrior2]

If you are gonna try regular grease, you'll have to remove the pad.

However, most generic grease's will be outperformed by the PCTC on the Coolermaster heatsink.

If you're looking for an alternate(but excellent performing /low cost heatsink) heatsink, look at the taisol units. I have one on my p3, and it performs within a few degrees c of my pal6035.

Thanks for the info Mike.

I am currently looking at alternatives to the Alpha since it is not readily available. Bummer is, I just found a site that had about a dozen in stock ( found them yesterday, but already sold out. ) Oh well.

Reading about HedgeHog, SupaOrb, and TaiSol, but still think I will just wait.
