I replaced the 2 x 92mm fans on the heatsinks to 2 x 120mm Gentle Typhoon AP-15s. Runs naked on my desk with no sound at all @ 60C.

You mind posting a picture of this setup? I am assuming that you are not utilizing the 120s from the ends. How did they mount?

Disclaimer: I just got my hair dryers and am looking to replace the noisy fans.

So you just put the 2 x 120mm fans on top of the heatsinks blowing down ... do they fit? I mean how did you hold them in place?

Also, did you connect them to the original heatsinks connectors on the board or hooked them to the connectors for the intake/exhaust fans?

Do you think 2 of these will do the job? Corsair SP120: http://www.directcanada.com/products/?sku=11180AC0334&vpn=CO-9050007-WW&manufacture=CORSAIR

Replace the 120MM fan with GT1850

not very widely common in EU Sad

hm.. that is not very high airflow (cfm) is that really enough? I would have thought more is needed..

Hmm I think the AP15 moves around 58 CFM. What kind of airflow are you looking at?

sorry, I was thinking of avalon fans while writing this

anyway I found an interesting fan:

quiet and powerful...

well.. I do not want to strip single.. as components on and under the pcb are less cooled then..

Well I'm pushing air through the heatsinks and it seems ok so far. No crashes or reboots since I got it last week.

So what you are saying is BFL designed it wrong?

I find that hard to believe.

What about venting the top of the case and making both end fans pull air in?

I though that too but did not want to cut or drill the original case of single... But if you do that some air shrouds are reccomended to push amd pull the air the right way and quietly.

Hi eestimees

From the picture, the "mod" looks to be made from metal. I don't have a metal sheet nor the tools to bend one if I had it in the first place, but I'm interested in modding the Single.

Do you (guys) think that a hard cardboard could do the trick? Is it safe to use cardboard in the first place? aka it doesn't catch fire from the heat.

Yes, it has been cut out from old miditower case. The heat on top is not so high, but i would not reccon paper or cardboard anyway.. For me it is too much risk.

Non steady state conditions tell you nothing about the cooling capacity of the system, too many things going on.

And by that you mean? Sorry but english is not my 1st language.

Steady state typically means when everything in is the same as everything going out. In this case, when the heatsink gets to a constant, stable temperature, effective steady state is reached.
