I re-did my entire primary system recently from a multi-fan "screamer" to a much more quiet setup. For a long time, the noise of the 60mm & 80mm HO Deltas and 120mm Papst HO intake/blowholes did not bother me much as long as I ran fast and stable. After awhile, the noise started to bother me more and more. I tried many possible solutions, including a Koolance watercooled case. The Koolance works well for me up to 1400MHz, but I knew my primary 1200 AXIA T-Bird could do more, and I ended up not being satisfied with 1400MHz.
Anyway, I upgraded to the EPoX 8K7A+ recently, and was able to up my core voltage to 2.0V without modding the board, and have been looping UT, Q3A, running Prime95, etc..without any crashes at 1575MHz. I knew my MC-462/80mm Delta HO could handle the heat, but as I said, I wanted quiet, and not having the hassle of removing the mobo to change HSs if I wanted. I purchased an
Akasa Silver Mountain HSF (a silver coated copper HedgeHog with a better clip) that came stock with a 60mm Delta installed blowing down, even though the HS has a shroud. In my experience, I have always found that shrouded HSs work better with the air pulling from the bottom (sucking) than blowing down on the HS.
I have already looked into 60 to 80MM fan adapters before, and purchased one of the
expensive metal Japanese models from Plycon. I also was very interested in the design/performance of the
Panaflo FBL low noise ring cage fans. I purchased a few of the 80mm models, and found that they work well, and are pretty quiet.
I have my new case setup with 92mm very quiet Sunon fans. (2 front intake, 1 top blow hole, and one rear exhaust.) My Enermax PS also has a quiet bottom intake fan and rear exhaust.
To make this long post shorter,
🙂 with the 80mm adapter on the Silver Mountain, and the Panaflo FBL set to suck air, it exhausts air from the ring cage (see link about the fan) up through the Enermax, and also right out of the rear case exhaust fan. I was quite surprised to reach a stable 1575MHz on a processor that would top out at 1500 1.85V before. I was in a hurry to get my new rig up and running, and did not install my Digital Doc5 temp probe to the core, but at 1575/2.0V Sandra Pro is reporting 46.9 Cel. right after a heavy load of looping games & Prime95. Even if the temps are 10 degrees higher than the inaccurate in socket mobo probe reports, 56.9 Cel. under load at that speed and voltage is not bad.

My whole system is much, much, more quiet than before. I can hear my hard drives, and my window unit AC is louder than my rig now, when before, my system with the Deltas and 120mm fans drowned it out. No freeze ups or crashes, no matter what I run. I even ran back to back Content Creation Winstone 2000 for awhile. I am impressed with the performance/CFM/noise level of the Panaflo FBL & adapter teamed with the Silver Mountain. I am sure a HedgeHog with the same setup and less expensive adapter (I have an acrylic case and like the "professional look" of the Japanese model) would produce similar results. There are other HSFs out there with better performance, but most have to have HO/high RPM loud fans to make them effective.
