I'm having trouble living with the noise coming from my processor's stock heatsink fan. I know other ppl are too, from reading the Feed back section on Newegg
http://www.newegg.com/Product/Product.aspx?Item=N82E16819103894&Tpk=phenom%20970

I don't plan on OC so I just wanna replace the fan. Can anyone recommend something quiet that fits on my stock heatsink.

e.g.

What size is the fan? 80x80mm, 70x70mm, etc? Also you likely have one with 4 wires (called PWM), correct?

I measured it in inches and converted that to mm and its 70x70 with 4 wires, correct.

Understood. Took a look at Newegg and they have no 70x70 PWM fans. That being said, even if you find a quieter fan, it will run maxed out trying to keep the processor cool (as much as possible). To get better performance (and noise levels) you really do need to go with an aftermarket heatsink/fan (a.k.a. HSF).

If you aren't comfortable removing to mobo to install and want to use the current mounting bracket, you could use a HSF like this one from Zalman:

It will cool way better than what you have now and will be quieter, as well as it will mount to the current bracket.

upon removing the side casing of my pc (which holds two fans) the cpu fan got really loud and hot. When I blew air on the cpu it instantly grew quiet. My pc case has room for 2 more 200mm fans. I believe i can make a big noise reduction if I install them.



I have to admit I like that Zalman HSF. I will certainly use that after all else. I prefer the simplest solutions...unless benefit out weighs of coarse.



The cheapest, simplest solution I can think of is more & better fans. I found 70x70 PWM fans (under case fans) on Newegg. Pls have a look at this one and tell me what you think.

Would it fit and possibly decrease noise levels alittle?

That fan is not PWM capable and will ikely be louder than what you have now. You can add the additional case fans as you indicated and that will help. A side fan, sucking cool air into the case and blowing it into the CPU area will definitely help.

but the Noise level is 37.25 dBA! that's double what came with the case...

Best solution

Yep, that is loud. If I were you, I would make sure all of my 120mm fans were installed and I would replace the CPU HSF (the Zalman would be good).

The problem with the 200mm is only the fan I sent to you will work with that case. Just the way it was designed.

I think you're right. I'll just get the zalman HSF and I have one spot available for a 120mm fan in the front. There is talk about a new 200mm fan from nzxt coming out that's quieter n with LEDs but u no rumors...


Thanks so much for ur help today.. U rock

K apparently Zalman HSF is super noisy according to the feedbaCk on newegg....


The search continues....

I'm gonna buy it along with arctic silver thermal compound, remover, purifier..


Just gotta make a quick measurement first :D

It is a good HSF. I use the same one in my home server and it is very effective.

Sold. Nothing like testimonial to seal the deal. I presume I'll be reaching in the back of my mobo to install a back plate? I'm okay with this. I also bought a Aero Cool 120mm case fan http://www.newegg.com/Product/Product.aspx?Item=N82E16835129052

It's gonna be so much fun i'm gettin chills

No backplate. It will actually use the existing AM2/AM3 mounting bracket that your OEM HSF attaches to.

OH even better

Gotcha.

Everything installed! I ran into many problems though..

1st my stock hsf came off with my cpu still attached (with the lever arm still down!) the pins on the bottom of my cpu where bent out of place..and the thermal compound was stuck tight.

I decided to place everything in the sunlight to warm it up and I was able to pry them apart with a dull knife. Then I used the knife tip to gently position the pins back into place one by one. Luckily only about six were bad..They are VERY sensitive..I used extreme care closing one eye for 2d focus.

Then of coarse my little black cat jumped into my case and laid down like a cpu. She holds her own abilities in such high regard...

After that, installation was a BREEZE. Thank you for the recommendation. It snapped in there so easily. With out your help I probably would have gone with a hyper 212 like everybody else and that was going to be a beech! compared to this.

It looks so awesome. Idle temps are the 34 C (same as before) but games are now 44 C (compared to 56 C before). But above all its so quiet it's such a relief...

i kinda freaked out at the beginning but it all turned out okay and i'm smarter for it.

Good on you COLGeek
