P4 3.4 Prescott overheating

Ok i Have a P4 3.4ghz Prescott - and im am getting very worried! I went out and got myself a Zalman LED Fan Cooler (CNPS7700-CuAu - Not sure). I went from 60 idle / 80 load to around 48 idle / 60 load. Its way too hot! I know these P4 prescotts can get hot but wow!

Is it ok at that heat? If not... Anything i can do to get it lower! I have 4 case fans too!

If there is a product (e.g. water cooling) which one?

Thanks

I nearly didnt post in here because of the extremely rude ending to the tile of the post. In future please state your problem concisely and dont put any crap on the end.

Choose some good quality thermal grease. By good quality i mean `arctic silver 5`, nothing else.

Choose a nice big cooler, perhaps the Zalman P4 flower cooler with bracket fan? That should cool it to really low.

If not, i dread to think about someone taking this advice, do what my friend did, and rig up some cardboard tubing between the cooler fan and an air-con unit...

Dont go water cooling, it invalidates your warranty, unless you've got money to burn that is...

Well, you have a good start, dropping your initial temps by a good 20 degrees.

What kind of thermal compound did you use between the heatsink and the processor? You could try lapping said heatsink-- polish the base where it contacts the CPU, which will maximise contact between the two and improve heat-transfer.

You want to maximise the air flow through the case as well, ensuring there are fans blowing in and out in relatively equal proportions. Generally speaking, you want a front or bottom fan blowing in and one at the top blowing out. Larger fans make less noise while moving the same volume of air that a smaller fan would.

If you want to talk water-cooling or peltiers, then I'd suggest a change of venue-- my buds on the hard side (DevHardware) have a forum just for cooling and there are some real experts there: PC Cooling Forums

Any estimate on how much it may drop the degrees... Is it safe for this processor to run at this speed?

heh, its safe for the processor to run to 97 deg. C

Well higher than that, but for safety reasons, 97 is fine

So at 48-50 idle and while on games upto 65 (all oc) its fine Im glad! I dont have to spend money on other things

I have another question though..

I have plugged a 20 pin PSU connector ro my 24 pin connector on my motherboard. Since i changed psus on standby i get errors and microsoft say its a power failure or damaged hardware. I have ordered a 20 to 24 pin converter for my psu.. will that solve my problem?

yes.

Although i still recommend getting the arctic 5 its worht the $10.

AMD specify all motherboards for their processors must have a chip that turns it off at 97 deg. C. but it can go a bit higher safely
