60mm to 80mm fan adapter

[OpK Chowdy]

My pc is loud. really loud. I want to quiet it down a bit..and 80mm fans are not too noisy, but my 60mm fan that runs at 7300rpm is. I have a coolmaster hcc-002 or something like that. It's the same as the popular heatpipe one, only without the heatpipe. Anyway, the fan is rated for ~30cfm. I have a 80mm fan that's rated for ~30fcm. Could i buy the little plastic adapter that allows you to put an 80mm fan on a heatsink made for 60mm? I'm not worried about the ramifications of my case, just if the thing'll perform as well. 30fcm is 30cfm, am i right?

If the fan isn't good enough i could always order a good 80mm fan that pushes more air.

This is important to me because i OC and i am on like borderline temps here. If it matters my temps are 46C idle, 48C during normal load (like at this moment), and 51C after extensive heavy load use (gaming). My case has a temp of 37C and can climb up to 39C during various points of the day.

Any info'd be great. Thanks.

you will lose some performance through the resistance of 80mm airflow being funneled through a 60mm opening.
it is better to have a higher CFM 80mm to go down to a 60mm as this will then become relatively the same actual airflow

I did just that, a while back when I had a coolermaster sink.....
I just slapped on a 60/80 funnel & bazzed in any old tosh cheepo 80mm fan & it hushed the comp up a treat....... No benifit cooling wise tho'

I suggest that you will need more like 40 cfm than 30 to cool properly. The 60/80 adapter will cause some airflow restrictions. Try to raise the adapter up away from the heatsink fins about 1/4th inch...this will relieve back pressure on your fan, which will allow it to generate the maximum airflow it is capable of.

An 80 mm fan that will deliver 40 - 45 cfm will usually run around 4000 - 4500 rpm, and is reasonable in noise...it will not be totally quiet however.

This solution does not seem to hold any water doing the maths
but I would get one of these:

SUNON 60mm 3pin fan. This fan is very quiet and very dependable. It is, in our opinion, the best all around fan we carry. It moves a stout 23.5cfm of air all the while being almost silent about it. We've never received a noise complaint on this fan. Also, this is one of the highest quality fans anywhere which is why we seldom have to warranty one. The fan does have a lifetime warranty They just run forever. The fan is 60x60x25mm with mounting holes 50mm apart side to side. It is ball bearing and has a three pin connector. The cost of the fan is $7.00 plus S&H.
SPECS: 4300rpm, 22.5cfm, .17 Amps, 2.0 Watts

I have used these as replacements for Coolermaster fans & they work OK www.1coolpc.com

Absolutely nothing....if....there is some discription to the alleged "lifetime". It could die a horrible death in two weeks, and when you try to RMA it...they could say "it died because its lifetime had run out".

If something is advertised as being able to run forever then it wouldn't need a lifetime guarantee now would it? That's like saying it will run forever if it doesn't break down. Duh!

I'll get the highest cfm 80mm fan i can find and a nifty adapter. There are several adapters, which one is the best?

I thought you wanted to quiet down your PC.

If you just want to reduce pitch, ignore that above sentence.

A fan funnel with vanes in the middle is the best for directing air vertically down to the heatsink fins and does reduce back pressure somewhat.
