60mm to 80mm fan converter?

[dezekiel]

Has anyone tried those 60mm to 80mm fan converters? You can stick an 80mm fan on your Heatsink. I think I might try one on my Alpha 6035 instead of upgrading to a noisy delta 60mm fans.
I wonder how much vibration thoes 80mm puppies put out?
I can see the whole heatsink falling loose...:mad:

I have seen a few reviews of these and have not been impressed. It seems that the 80mm fans can't work to their full eficiency as they are trying to force/pull the air through such a small opening. This leads to them performing worse than using a standard 60mm. You may be better of ducting air either to or from your heatsink from outside the case.

tril0bytes werked much better thn the comercial ones. The commercial ones don't make a slanted opening (like a funnel), they just get a pice of plastic that is 80mm sqaure and cut a 60mm circle in the middle.

Ask tril about his fandapter.

Cue tril to outrageously pimp his fandapter :)

Hi dez, Yeah I've heard mixed reports about them too. Although I had brill results from the one I made for a PEP66. But a couple of important factors there, the PEP is designed to have air sucked through. Ya gott have the fan this way, cause ya cant blow the wind into a small hole, but you can pull more wind through. Also, I was using it with a pelt on a P3, I think the better airflow really made a difference to the t-cold, maybe this wouldn't be so much of a thing with just cooling a tbird. I dunno, clearly some folks aren't impressed and others are - mine worked well.

I did a writeup about it here:

Here's a solution that works pretty well in lieu of an adapter. Take a 80 mm fan guard and using 1/4" spacers attach guard to heatsink w/ spacers holding the guard above the the heatsink. Then use nuts and bolts to hold 80mm fan to fan guard. By holding the guard up off the heatsink it helps eliminate the dead spot in the middle off fan. Sometimes you may have to spin the guard around to get every thing to fit properly. I use this on a Swiftec MC-370 alu cooler w/ 80mm Sanyo Denko on T-bird @ 1.53.Hope that helps.....goldie:p

Last night I changed the 60mm fan on my PEP66 (sucking away from the fins, of course) to an Evercool 80mm via a Plycon adaptor. The 60mm was not the YS-Tech that normally comes with a PEP66 'cos it was too loud, but the 60mm that comes with a Taisol 742 which is very quiet and moves 21cfm.

The Evercool is 29cfm and slightly quieter. My cpu full load temperature has not changed (37C, delta over he case temp of 8C) despite the supposedly increased airflow. This is probably because with the case closed, the top of the fan is within an inch of the case side panel. Now all I need is a hole with a duct but I'm not cutting a hole in the side of a Lian-Li!

Having made the change, my main PC is virtually silent.
