Question about Coolermaster hsf

I have a AMD Tbird 850 system that uses a Coolermaster hsf that was provided free with the cpu when I bought it back in August of last year. My temps seem to have been okay 42-43C idle, 49-50 under a full load. But ever since I installed the United Devices cancer research client, coupled with warmer summertime ambient temperatures, the thing is hitting 52-54C just sitting idle. I think this may be causing some strange instabilites that I have been experiencing lately. The cpu is not overclocked, and the hsf I beleive is rated up to 950 Mhz. My case is a Tornado 1000 from 3dcool.

I would like to experiment with the hsf to see if which gives me better temperatures sucking/blowing.
Currently it is sucking, but I think that may not be giving the best cooling because the case side panel has two 80mm fans blowing 43cfm's into the case directly over the cpu. I believe this may be having a negative effect on the small fan on the heatsink.

Exactly what steps do I need to take to reverse the direction of the fan? It is a three-pin fan plugged directly onto a fan header on my A7V motherboard. The connector is slotted so it can only plug into the pins in one direction. Do I have to switch some wires around or something?

Thanks,

Gamble

Just turn the fan upside down for it to blow. Isn't that case supposed to be a "overclockers" case? AMD recommends one intake fan and one exhaust fan, so, I'd have the fans on the side panel sucking air out of the case.

Your coolermaster's a stock fan that comes with RETAIL AMD chips. probably 5H11 or something?

Turning it upside down would reverse the air. arent' all HSF designed to blow? or just mod it do 80mm fan. That'll cool it right down.

Compellor,

AMD only recommends one exhaust fan and says intake fans are usually not necessary.
