I am looking for a replacement fan for my AMD Athlon II X4 640 processor as it is very loud. I DO NOT want to replace heat sink, just the fan that is on the top of it.

Here is what I found via Amazon:

My motherboard is Gigabyte 77OT-USB3

Most AMD heatstinks use 80mm fans, What heatsink is it (pics).

The stock one that comes with the CPU.

I measured it and it is 70mm going accross in all directions and 80mm diagonally.

that says 80x80 mm. i measured mine to be 70x70

It is still going to be loud, replacing the whole cooler is the best way to go unless you are using a system that is low profile like a slimline or a itx. The noise is generated the voltage is raised to 12v in order for the fan to reach a higher rpm to increase airflow due to the heatsink below isn't keeping the cpu cool enough to begin with.

Get a large cooler that will still fit and mount properly then noise shouldn't be an issue as the fan on a larger cooler won't be running at full speed.

Im not going to get a new cooler. Its just the fan thats making the noise.

If it is just the bearing making occasional noises then just take the fan off, clean it and then oil the bearings.

I want a new fan. i just need recommendations on what one to get.

Hi :) 

Hes gone because you were NOT listening to good advice....

The original heasink/fan from AMD is excellent...ANY other fan you find will be JUST AS LOUD or LOUDER...

And there are very few fans that will fit other manufacturers heatsinks....

Just BUY a new heatsink and fan if you must...they are not exactly expensive...

All the best Brett :)

I'm trying to say that the heatsink is good but the fan is really noisy. I don't see how geting a new fan would make it noisier if I get a silent one?

Most fans won't be quiet at max speed, for some reason you fan is at max speed thats why its loud, we need to figure that out first.

First check temps with core temp-

Wait for it... Replace the the heatsink! Preferably with one with a larger fan. 70-80mm fans (or small fans in general) are inherently loud, no matter which one it is.

A Cooler Master Hyper TX3 should do the job. COOLER MASTER Hyper TX3 RR-910-HTX3-G1 "Heatpipe Direct Contact" 92mm CPU Cooler Still just 92mm, but it should be much quieter than any fan that you can put on the stock AMD heatsink. Also, it doesn't screw it, it just uses the clip mechanism. There, no reason not to do it.

Would I need to re apply thermal paste to cpu for that? If so How do I do that and what do I need to buy?
July 23, 2012 7:32:59 PM


All the stuff you need should come with a decent brand, low cost cooler, and yes, you must remove and re-apply thermal paste. There are lots of written and video guides on the net on cooler installation ... google is your friend :) 

Good luck! ... you really will be much happier with a new cooler. Small fans by their nature are louder than larger fans because they have to spin faster to move the same amount of air over a heatsink surface, even if they claim to be "silent". 70mm is an odd fan size to find and replace too.

The reason its noisy is because its smaller and therefore has to spin faster to move that amount of air. Did a google search and found a few 70mm fans but I doubt they would be much quieter.

May I recommend the Scythe Shuriken, It has a stock appearance and is extremely quiet.
