AMD Athlon 1.2 <---- high temps!

[Airwolf28]

Greetings all....

I have an AMD 1.2 ghz Athlon on an ASUS A7v266-E motherboard with 512mb of DDR ram. The case is a mid-size ATX with an adequate amount of fans. Fan placement is listed below. The CPU fan is a copper "tornado" fan running over 5000 rpm's. I used the compound tape between the CPU and fan. The CPU is NOT overclocked, runs 1.75 volts, jumpers are set correctly, etc. This thing is cooking at an average of 65c to 70c in WinXP under normal operating conditions. Obviously, when I run a graphics intensive game, the temp increases dramatically. AMD rates their CPU's over 1ghz @ 95c, but it just seems a bit hot to me. Any ideas on what to do or how to cool this thing down? If I upgrade to the Athlon XP, will that make a difference? Thanks in advance!

AMD Athlon 1.2GHZ
ASUS A7v266-E motherboard
512 DDR ram
two 40gb 7200 Maxtor HDD's
Visiontek GeForce4 4400 (awesome card, btw!)
SB Live OEM
Sony CD-RW 24x10x40
etc., etc.,

Fans:
1) CPU Fan (5,000 rpm's, copper core)
2) chipset fan on MB (came with board)
3) front case fan (sucking) @ 4500 rpm's
4) HDD cooling fan in 5 1/4 bay (3 small fans sucking in)
5) 400watt power supply with dual fans blowing out of case
6) case fan on the back of the case near the CPU (between power supply and expansion slots)
*** all airflow seems to go from the front to the back of the case ***

NOTE: I had a 300w power supply, ECS K7VZA motherboard, and 512 of PC133 ram a week ago, but the motherboard failed. I upgraded to the ASUS board, RAM, and 400w power supply and kept the 1.2ghz CPU. This is what happened as a result. PLEASE HELP???????????

You currently have more air going in than out, it seems. This is wrong.

You should Create negative pressure in the case - at the very least have equal in/out CFM values.

Also, consider an all copper heatsink with Arctic Silver thermal paste.

My 1Ghz AXIA does 1.53Ghz @ 47C max load, so you have to improve your cooling. Concentrate on the CPU HSF, then, if your Case temps are high, sort your airflow. Many H/W sites have articles on this matter.

You need thermal paste, preferably arctic silver III. The thermal pad will add 5 C over arctic silver at least. You should be getting temps around 45 C to 50 C idle. If it remains too high, try lowering the voltage on the chip and stability testing at the lower voltage. I have my TBird 1.2 at 1.65 volts running at 36 C idle right now (29 C ambient).

What's your case temp? (could be reported as system temp).

My cpu temp dropped 7 Deg C @ Idle by just adding arctic silver. It was 35 C at Idle and now it is 28 C. Under load it used to run 47-48 C now it runs at 40-41 C. That stuff will even make a crappy HSF cool well. The key is using some print cote solvent on the mating surfaces untill the Qtips dont get black anymore when you rub them.

I've messed around with two 1.2GHz AXIA chips that overclocked really well but ran really hot even unoverclocked. Check your case/motherboard temperature. If your CPU is much higher than case temperature and case temperature is barely above room temperature, then you need a better cooler. If your case temp is pretty high (a LOT above room temperature) then you need better case ventilation, then once case temp is lower, see if CPU temp is much above case temp.
