Still having cooling problems...

AlmightyOne · Mar 12, 2001

Hi everyone!

I got rid of my lousy CoolerMaster cpu-fan, and by recommandations from you I bought a GlobalWin FOP-32 cooler which should be much better, but I'm still having cooling problems.
My CPU temp. has fallen, but only to 62C and MB temp around 40C. Why am I'm having these problems? The cooler should be placed alright and have perfect contact with the CPU.
I'm using an Aopen HQ45 case and I have ordered a Vantec system cooler to make a better airflow in the case, but I'm still wondering if this will help me with my problems
The temperature in the room where my computer is standing is aroung 23C and there is plenty of space around the case.
Please comment...

Are you using any thermal compound between the CPU and heatsink?

If not you should.

If so, make sure that you're not using too much, only an extremely thin layer is all that is needed. More than that and the thermal compound actually makes it worse than not using any.

AlmightyOne · Mar 12, 2001

I'm not using any compound. There was some pink stuff on the GlobalWin heatsink covered by a piece of plastic. I removed the plastic and placed the cooler on the CPU and that was all. I have heard from hardwareengineers, that you shouldn't use any thermal compound like Artic Silver when the the pink stuff is already on the heatsink, but is that true?

You definately do not want to use both greases on the cpu.

as far as your temps, what motherboard are you using? What bios revision? and your mb temp is pretty high, you may want to work on cooling that down, which will help further cool down cpu temp.

I'm using an Asus A7V133 bios revision 1002A-1. As I told earlier I'm waiting for a Vantec PC system cooler, which I hope will cool the case and by that also the CPU.

Mikewarrior2 · Mar 12, 2001

Umm... do you have a link to the vantec pc-cooler?

The link for the Vantec cooler is:

Judging from your homebuilt, you can run circles around my knowledge base but what the heck.....

You sound convinced of the temps you're getting. I would do what I call a reality check on those temps by letting your system sit open overnight to equilibrate with the ambient room temp and position a digital thermometer next to it. Power up and go straight to your bios and check your temps. They should be very close to your digital thermometer within a couple of degrees both for cpu and mobo. At least that's what I see with my P3750@915/Soyo6BA+4.

My second reality check is running someting like cpuburn and feel the hs. MBM5 (and MBM4) shows cpu temp of 36C for mine.The hs feels like it's about my body temp, which is about 37C. Ofcourse cpu temp is not hs temp but they should be close enough for practical purposes.

I have a +5 compensation on the MBM, only have the psu fan and the Sunon 60x25. Right now, the Sunon is running @ 5V/2000rpm while I surf the web and my cpu temp is 26C and my PEP66 feels cold to the touch. No other fans. That's good enough correlation for me.

What I'm getting at is that I'll have to be convinced of the cpu temp of 62C. I think that's pretty darn hot. Mine seem to lock up at 50C. I have to run the Sunon at 12V then. Good luck.

The heatsink on the GlobalWin is hot, very HOT. So hot that it's annoying to hold your fingers at it for too long. So I don't think it's incorrect readings by the BIOS or by AsusProbe. My system runs 100% stable and I haven't had any problems by lock-ups or blue screens of death.
Mikewarrior recommended a big fan like 80x92 to get a better airflow instead of the Vantec Pc air circulation cooler, and I really think this would help.

Almighty One,

I am getting temps around 46-48C on my A7V and T'bird 800 at 945 and FOP-32. I bought the chip and board from my brother after he said it was locking up on him. I asked him if he used thermal compound when he put the heatsink on, and he said no cause the he did not have any. Needless to say, I did and it runs great with no lockups. I get a BSOD when I run it a 1GHZ, but this is fine.

When I was playing inside the computer like I do every other day, I did not plug the cpu fan back on, and I got into Windows before I remembered. When I touched the heatsink it was quite hot. When the fan is running, it is warm to the touch.

I would suggest cleaning the thermal pad material off the heatsink with Goof Off which works great, and trying thermal compound. Even try the $1.99 tube from Radio Shack.

I agree with Galileo. Double check those temps.

<< The heatsink on the GlobalWin is hot, very HOT. So hot that it's annoying to hold your fingers at it for too long. >>

If that is the case, then you indeed are gettign 55c+ temperatures.
60c feels close to burning hot (you can't hold it for more than 1 second)

Do you have any other case fans?

Mikewarrior2 · Mar 13, 2001

Galileo,

What isn't there to believe about high temps? High end T_birds and P4s all generally run in the 40-60C range on anything from a good to mediocre heatsink. Put a substandard heatsink on them and t-birds will be pushign 70+C in core temp. Just because of the crap socket-thermistors not showing this does not mean the cpu's aren't running that hot.

AlmightyOne's case cooling isn't spectacular(in fact, i do not believe he has any case fans installed yet), so that explains the 40C mb temp, because his case's only airflow is being pulled in through the power supply fan. figure a 35C+ case temp, and an fop32-1 heatsink and 62C isn't really that far fetched. His heatsink isn't getting enough "fresh air" to remain efficient.

Galileo · Mar 13, 2001

There you go. Maybe there isn't that big of a problem after all.

Just the same, some experimenting is what I would do before I settle down with my setup. I'd install the cpu fan to suck, direct the hot air through a funnel using a rolled thin cardboard to the side of the case, make a temporary side panel on that side with a stiff cardboard with a hole in it and duct tape the funnel into it so that the funnel don't touch the fan and all and bother your cpu/hs contact. I would take temp readings then and see what that does.

I would then add variables to that set up by using a higher cfm hs fan and then add a case fan to the scenario.

I'd also do what you have now and only add a case fan and then a larger cpu fan.

Last, I'd set the cpu to blow again and let it suck room air through the funnel. I'd write the temps every changes I make.

I might also put a fan on that cardboard side panel and let it blow directly to the cpu area instead of installing it in front of the case.

My Duron 800 runs @ 22-35 C. Is that acceptable/good? What's a dangerously high temperature?

Mikewarrior2 · Mar 13, 2001

depends on several factors:

motherboard /motherboard bios
ambient temp
heatsink

Galileo · Mar 13, 2001

Mike,

That is a very non-commital answere. Assuming that wQuay's temp sensors are reporting those temps accurately, those temps are under full load, and his room temp is 18C-22C, what would you say?

AlmightyOne · Mar 13, 2001

Listen everyone. Today when I got home from work, I upgraded my BIOS to the lastest version 1004, and the temperature fell in the BIOS from 63C to 55C!!! Why is that? Has Asus made any mistakes?
I will get a fan to suck fresh air from the front, hope that'll help too!

--=Almighty One=--

they call mr big · Mar 13, 2001

do you have case cooling??? get some 120 mm fans in there! yeah asus has problems with temps, bios update usually fixes it

Mikewarrior2 · Mar 13, 2001

Galileo,

Its non-commital because that is the nature of socket-a readings. Socket-thermistors are never accurate, sometimes they are good at guessing, but you never know. In general his temps are not too high, but you never know.

If he had provided the a case temp of 22C, then his temps are fine. if his case temp is 0C, and his MB is an MSI/iwill board, then he's got problems. If his case temp is 10C, with an MSI/iwll board, again, he's pushing into trouble area's. But he never provided motherboard or an ambient case temp.

Mike

wQuay · Mar 13, 2001

Ok, it just read 32/CPU, 24/MOBO. Does that ratio sound right? As for the case temp, should I just stick a wall thermometer in there?

Mikewarrior2 · Mar 13, 2001

Yeah, its fine... you're nowhere near too hot. Btw, is that an MSI mb?

Mike

wQuay · Mar 13, 2001

Ok, thank you. iWill KK266A.

When i replaced my Enlight 7231 with a AOpen HQ45, my cpu temp went from 46 to 52! This is when running RC5. First i installed a second fan in the front of the case, that didn't help, then i put it in the back of the case, above the psu, but that didn't help either.

Does anyone know if the psu runs very hot by itself? What else can be wrong?

Mikewarrior2 · Mar 14, 2001

You had no fans in the enlight?

Has the room where the computer is changed in temp drastically(to the tune of maybe 5-6C)?
