Please suggest me a better, quiet fan for heatsink (60mm)

DaRuSsIaMaN · Post by **DaRuSsIaMaN** » Fri Jan 22, 2010 5:03 pm

Hello, all. I'm looking for a 60mm fan for my heatsink. Yes, I did look through the SPCR's Recommended Fans page, but it stops at 80mm. And I do have a small heatsink: Dynatron BH-610. There are very few choices in socket A heatsinks these days.

So, I found this fan, for example. However, it's not very quiet. A quiet alternative, like this one, is a bit wimpy on the air flow. Is there anything maybe in between those two? Maybe not quite as quiet but with more air flow?

Also, anyone know of any fan that will fit a 60mm spot but is actually larger? Kind of like this 92mm which fits 80mm slot?

Any other suggestions? Thanks

The 2 fans you linked run within 300 RPMs of one another (2000vs2300), so the airflow is probably going to be within 15% contrary to what the specs show on the site. My guess is that the noname fan company is being overly optimistic in its specs. Having said that, fans of that size spinning @ 2000 RPMs are not going to be very quiet. I have a Scythe 80mm fan in my PSU @900-1000 and that's comparable to a good 120mm @ 550, which is quiet (to my ears). I'd be hesitant to run a 60mm @ more than 1200RPM.

In your situation, I'd probably get a 80mm or even 120mm and improvise some way of fixing it to the heatsink.

If I'm understanding the photos.....the fan will be on top and blowing down?

I believe Scythe has 40 and 80mm.

I quite like Noctua myself. They have 80, 92, 120 and 140mm.

Oh....you could also explore here for ideas......

But I need 60mm, not 80 or 92... or to figure out how to fit an 80mm onto a 60mm-ish heatsink. Which I'm not sure how to do

Oh, okay I see. Those adapters in your second post... ugh, going to have to cough up more than I'd like going that route.

I agree. Get an 80mm and forget the adapter. Years ago I made my own 80 to 60mm adapter and did a lot of testing with the 60mm, the 80mm and adapter, and then the 80mm in free air suspended above the heatsink. Losing the adapter only cost me about 2 or 3 degrees C. You could use Mike C's method with a rear slot cover converted into a mounting arm (shown in the very first review on this site, modding a P4). Or you could run wires from front to back of the case and through the fan's mounting holes to hang it above the heatsink. It doesn't have to be mounted to the heatsink itself, and if you manage a type of soft or suspended mount it may even be quieter.

There is another way, if your heatsink has conventional fins. Bend the fins out to the side until they are 80mm wide and mount the 80mm right on the heatsink. I've found big old woodscrews will grab onto the gap between the fins for mounting. A wide scraper or any stiff thin metal device pushed between the fins works well to bend them out. Let the fan hang over one side of the heatsink; it can help cool the voltage regulator chip or your ram.

I second what DanceMan said, but there is no need for bending fins: just screw the fan in the upper right corner. It will help you cool the northbridge and your voltage regulators.
I've been doing this for years (since amd k6-2) and it is way better than any screaming 6cm fans.

The silenx is quiet, but doesn't push a lot of air.

What chip? What case? What temps?

There may be no need to mount fan directly on the HS, allowing you to use a bigger/more quiet fan, and skip the adapter.

In my experience a 60x60x25mm fan has blades 3x wider than the usual 60x60x10mm fan and blows 3x the air for the same rpm.

I doubt you would regret upgrading to a new HSF with a larger fan. Perhaps something like this:

Hi,
I use a Papst fan (60mm, slim). It's decently quiet but doesn't push a lot of air.

Hi DaRuSsIaMaN,

I second xan_user's post - what are you trying to cool here and what is it's TDP? I'm guessing that it will be quite low if it was supplied with or you are intending to use a 60mm heatsink.

I recently had a lot of success improving the performance of a passive NT01-E heatsink by using an old AMD cpu fan (from a socket A I think) and running it at 5volts. It's very quiet, and the little airflow does what I need.

If your thermal requirements aren't too high, undervolting your existing fan (assuming you have one) could help keep the noise down. Just keep an eye on temps by stressing the system.

It also doesn't cost anything to try.
