Upgrading HSF on Athlon 64

I have an Athlon 65 3000+ socket 939, which I have a little overclocking, but I am scared to really test the limits with the stock HSF, I was wondering what the best HSF is for the socket 939 setup.

I was looking at this one, but it's a honker for sure...but quiet I bet.

Arctic Cooling Freezer

That is what I'm leaning toward...what are your suggestions?

I'd say use the stock heatsink. If you HAVE to go aftermarket, then Zalman CNPS 7000B AlCu.

If you do upgrade the heatsink fan. Remember to

run the computer in prime for a few minutes

Then shut down and twist the heatsink off (side to side motion).

You don't want the cpu to come off with the heatsink without the mobo latch being set to open.

Did the cpu come off without the latch intact? If so...then you might of damaged the cpu pins or you should see small cracks on the cpu silicon itself. This will lead to repeated computer shutdowns and restarts (instability). Overclocking would be out of the question.

I haven't had any issues overclocking with the stock HSF. I'm not talking about the older, better quality, copper/aluminum HSF that AMD used to package with the Athlon64 either. I'm referring to the newer, cheaper, all-aluminum HSF that AMD is shipping with it's newer processors.

If there's any complaint I have about the stock cooler, it's the noise. It's a little louder than what I'd prefer.

A question for people using the Zalman with A64 motherboards.

I just installed a 7700AlCu on a Shuttle AN51R a few weeks ago, but it took a bit more prying than I would have liked to get the stock mounting backplate off of the board so I could install the Zalman backplate. I was actually afraid that I may have damaged a few traces on the back of the mobo, but once I installed the cooler the mobo seemed to run just fine.

Is there any trick to getting a stock backpate off that is attached to the board with adhesive, some method that is a bit less scary than prying it gently off with a screwdriver?

WHAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAT? DDDDDDDDDAAAAAAAAAAMNNNNNNN!

*Cries*
I feel like an IDIOT! !!

Now I know why I can't get my heatsink off! Crap. Crap. Crap!!!!
I'm gonna try your twisting method. I got a zalman7700 alcu (120mm) so it's kinda tight.

If the stock backplate was affixed with a glue like substance you can heat up the backplate with a hair dryer for a couple of minutes which will soften up the glue and allow you to remove the plate much easier. Tap on the two screws a bit, which loosens up the backplate more if you are able to. That is what I did on my MSI K8N Neo4.

I had to read this over and over again (because of syntax) to understand what you meant. Now that I think I understand what you're saying, this sounds like wonderful advice.

Are you saying, in other words, heat up the CPU first (running PRIME or some other CPU intensive application), which will "loosen" the adhesion between the CPU and heatsink, and, after shutting down, open the CPU latch, pull off the HSF in a side-to-side motion thereby decreasing the risk of damaging the CPU ???

Correct ???

OR are you saying that the CPU latch should be "locked" as you slide the HSF off the CPU (in a side-to-side motion) ???

Thanks for a reply to this question !

You are understanding him correctly, I had to read it twice as well to understand what he meant.

As for the Zalman 7700 not being usable fon Socket 939, that isn't true. The mounting mechanism on all 754/939/940 boards is exactly the same so any hsf that fits one of them will fit all.

And if you're getting the 7700, check if it's compatible with your motherboard first, it's rather large (same as the Thermalright Xp-120, which is a little better, but also more expensive).

With the rare exception of course e.g. My MSI Master2-FAR Dual skt940 board uses Xeon 603 mounting and cooling. Why? I have no Fin' clue.

SVC has a much better price with a 92mm fan included Great cooler, great price.
