Swiftech MCX462-V question

[FastRedPonyCar]

Ok guys. Question here. I've got a system using the abit nf7-s2 mobo and an amd 2600 mobile cpu. the voltage is right around 1.7 and clock speed is at 2.2ghz.

I had the arctic cooling hsf for a while (found here)

and it had the cpu ideling at 49*C with the fan at it's fastest setting. Not the best temperatures but this was to be expected from a rather cheap hsf but now that the MCX462-V is on along with the thermaltake dual storm 92mm fan at full speed, the idle temp is only 5*C cooler.

There are guys on other forms with this same setup and cpu (only theirs are clocked at like 2.3ghz) with temps still like 15*C cooler than mine. The heatsink (as far as I can tell) was put on correctly. It was nice and snug and I followed the instructions. The heatsink itself is actually COLD to the touch whereas the arctic cooler was rather warm. I pulled the swfitech off after a while and verified that the thermal paste had been smeared onto the base of the heatsink which tells me that there's good contact between it and the core.

Just out of curiosity, I put the clock speed and voltage back down to default and the temp only dropped 2*C :mad:

The case is a small atx Antec case with a single 80mm fan in front, one of those chrome/aluminum 120mm fans in the rear and another 80mm fan on the side panel. all those are going at full speed. It's rather loud and the wires are all tucked away nice and neat so there is good air flow. I'm just puzzled as to why the temps are so high because it's not stable during prime 95's burn in. It peaks around 56*C. Room temp is about 71*F

Any ideas? :confused:

That arctic cooling HSF is a very good HS for the money. I have used them several times. I would not expect a 15 degree difference between that and any other HS in the same conditions.

Maybe you should reseat it again. Clean it well and use very ltitle paste. Are you using AS5? Have you read the AS instructions?

Another idea is to try putting the fan on the heatsink the other way round. See if that makes a difference.

The thing about onboard temp sensors is that they're very inaccurate and will never be the same in different peoples systems. I would say if you aren't having stability problems then you don't need to worry. However you are. It seems your overclock isn't stable. Try upping the voltage on the CPU and the memory and see if that helps your stability.

I have quite a few mobile chips here and one or two of them report some very strange temperatures from the diode. The one I installed into my HTPC yesterday gets up to over 70*C which, were it true, would be enough to make the chip extremely unstable at the very least. Instability generally seems to hit around the 55*C mark.

That being said if your unstable then it just might be that hot. Might be a good idea for you to clean off the thermal paste and re-apply it just incase theirs a hair or other such piece of debris interfering with the thermal interface. The fan needs to be blowing down onto the Whifty for best performance. Make sure you have the heatsink on the right way round.

I don't think you should need more voltage, that would be a very poor mobile chip if you did. All the mobiles I have here do 2.2Ghz minimum at stock Barton VCore (1.65V). One of them does 2.4Ghz at that VCore on air cooling.
