Hello all,
I got a new Athlon 1900xp that came with an AMD heatsink and CPU fan. I installed it like AMD said to. My CPU runs at 43-49c. The one thing I noticed is that the CPU fan is pushing air ONTO the heatsink, not pulling air off. Is this right? I always thought that the CPU fan was to pull air off the heatsink. Should I turn the fan around? I really want to cool down the CPU a bit.

Your thoughts?

This is fine, and far under it's max. temp. The only point you need to be concerned is when it gets past 60°C, although it's max. is 90°C.

Also, the fan should be blowing air <i>onto</i> the heatsink. It's more efficient in this manner. I would explain, but I'm still kinda out of it. :lol: 

Lastly, if you have case cooling (i.e. case fans), then you've done as much as you can, short of purchasing a better heatsink/fan. Tip for case fans: make sure the front fan is set as intake, while the rear is set as exhaust.

That's all...for now. :smile:

Most heatsinks use expulsion, lowing onto the heatsink, for cooling. Most are designed to preform best that way. You could use induction, blowing away from the heatsink. Generally the results will be less than that of expulsion.

Note: However some heatsinks <b>are</b> designed to use induction. To answer the question of which you should use would be determined by what heatsink you are using.

Since you are using a stock heatsink it is most likely expulsion...

Im using the heatsink that AMD sent with the CPU. I bought the retail box CPU. (came with an AMD fan and heatsink).

Thanks all for your info.

One last question, if I were to put a fan on the side of my case, would it blow air into the case or draw the air out?

Try using Volcano 7, it's around $24. I have a Soyo Dragon Plus with AMD 1900+ and a Volcano 7 heatsink. With Volcano 7, you don't have to mess around with compound paste. There's a round rubber pad that sticks to the bottom of the heatsink and all you have to do is hook your heatsink to your CPU. The rubber pad acts like a compound paste. Also, Volcano 7 comes with a heat sensor unit. If your CPU gets hotter, the heatsink will increase its fan speed. Plus the heatsink is copper, it conducts heat better.

YOu think that pulling hot air across the motherboard into the heatsink would work better than pushing cool air from away from the motherboard into the heatsink? So does Alpha, but many users have found turning the fans over to push has made their Alpha work better! Fans do a much better job of pushing air than pulling it. And because fans pull from the sides, they creat less airflow over the part of the heatsink that matters. Alpha uses a shroud to cope with that issue, but has still been proven wrong by many of their users.

What's the frequency, Kenneth?
