Hi all...

Just got my new PC, I waited four weeks because they had troubles with getting my cooler, which is an Alpha PLA8045 - I chose this one after reading tons of reviews... Now guess what - I paid like USD60 for it and my Athlon is still running hotter than my friends with some cheapo Spire cooler :(. Under full load it's now on 62°C with Board temp being 43° and it's still rising... What dou you guys think? Maybe those guys that assembled my PC didn't apply some thermal paste? Are the temps too high? I'm kinda arngry now that I waited four weeks and paid USD60 for a cooler that's even worse than some cheapo..!

BTW, the Vcore is set to 1.75V, resulting in 1.79V, the motherboard is the EPoX 8K5A2+, processor is XP2100+.

Thank you for any input!

Try VCool, it seems to dramatically reduce my temperature by almost 20 degrees F. I'm thinking there's something wrong with my airflow though...

I have an ALPHA PAL8045 with an adjustable Y.S. Tech fan set up to suck the heat OUT of the heatsink, mounted in a Lian-Li Aluminum case.
It has Qty (4) 120GB hard drives, 3 optical drives, a floppy, a Zip, Creative Audigy, and ATI Radeon 8500DV video. XP2100+ on an ABIT KX7-333R. All this crammed in the case cane generate some serious heat - But:

My computer runs at 37C system temperature, and the CPU is usually at 53.50C, but in really intensive processing gets up to 59C.
With a Panaflo as the CPU fan it would go up to 64.50, never saw it hit 65C but it got close.
With the ALPHA when it does get to 59C the temperature returns to 53.50 in about 2 minutes when intensive processing stops.

The installation should have been done with Arctic Silver as the compound, the plastic covering should have been peeled off of the shroud that sits on top of the heatsink - where the fan mounts (it's a white lining), and the fan should have been set up to suck air through it and not blow down.

Your case temp should be under 40C and you should be closer to 55C for the processor idle temp.
The critical temp for an AMD is over 70C with failure near 90C.

You may need a better CPU fan, and may have to add an intake fan if you don't have one.

Hi all!

I decided to use some 80mm fan to blow the air the CPU fan sucked through the cooler directly out of the case, and feed the CPU fan with fresh air from outside (ie. 40mm fan blows air to the CPU cooler/fan from the backside of the case, and the 80mm fan transports the hot air out of the case through the side cover). I guess (hope) this will make a really noticable difference :). What do you think?

I bought a HDD Cooler by Antec from BestBuy and modified it as an exhaust fan. It works somewhat good, sucking out whatever air rises to the top. Its good for a quick way to see how hot my computer is running, if its blowing hot air or cool...

Could that Epox board be showing the real core temperature instead of a socket temperature? Real temp inside cpu is like 15c higher than what socket temp shows. New AthlonXp CPUs come with thermal diode inside of them to show this real temp but most motherboard manufacturers don't use it to show temperatures because people don't understand it and think their CPU is overheating. So most of them concintue to show CPU temps with a diode planted below the cpu core which isn't accurate. So depending on motherboard and how your motherboard is set up to read temperature, you could see as much as 15 degrees difference with identical cpu/hsf combo. Find out if your motherboard is displaying temperature from internal CPU diode.

The board monitors the thermal diode, but just uses it to shut the system down in case of overheating, the temperature that is displayed is read from a sensor below the CPU...

Make sure your PSU has a grill in the bottom (or even preferably a second fan in the bottom) and that you have another exaust fan right below the PSU. This is the best combo and is what recommended by AMD. That way both PSU and exaust fan below suck out hot air coming off the CPU and let CPU cooler blow a fresh cool air over it instead of reblowing the same hot air. If you don't have an exhaust fan below PSU and your PSU only has grill in the back and not in the bottom, that could be your problem. There wouldn't be any good airflow and you would be blowing bascially the same hot air on CPU.

I have a lian li pc65, 2 front fans one rear and an enermax 365 supply with two fans.
My Mobo is an MSI kt3ultra2, fan temps taken through sysoft sandra2002.

My xp2100 with ArcticSilver3 and the retail heatsink (which looks quite decent and has a copper base) my temps seemed high. Idling after hours my proc was at 49c, 59-62c after playing UT2003 for a little over half an hour.

That seemed kind of high to me, so i put on an all copper Vantec sink i had laying around that had a 7000 rpm Delta fan on it that i couldn't bear to listen to in my old case. I mounted the fan from my OEM sink to the copper Vantec. The results were 49c idle, 54-55c after playing UT2003 for half an hour.

Then i put the Delta 7Krpm fan back on and ran it. 43c idle, and 46-48c after playing UT2003 for half an hour !

I guess those lour ripper fans really work... but i am putting the oem one back on till i get my 80mm adapter and whisper fan...
