Was looking into this fan for an HTPC build, what are your thoughts of the fan? Did you successfully undervolt it?
And thanks to the OP for a great review.
It's hard for me to give it an individual review at this point because I've been throwing the kitchen sink at a problem, as part of an overall cooling effort. Despite being huge, the Northbridge heatsink and the VREG heatsink on the Classified motherboard both run hot, or at least it seems hot to me, but I'm new to this.
At idle, I've been around 65-67Â°C on the Northbridge (BIOS reading), and around 50Â°C on the VREG.
The Papst fan is quiet enough that I can't hear it outside my case, and I haven't even tried to undervolt it yet, it's running full speed (16dBA, 11cfm, 2650rpm).
If you need something in a 60x60x15 size and 11cfm is enough to accomplish your goal, then I would recommend this fan. I haven't learned enough about fans yet to really understand 'static pressure', but this fan doesn't seem to have much cooling ability when pressed up flush against the Northbridge heatsink. At the moment, I have it in a push-pull configuration, the Papst 60x60x15 pulling on one side of the NB, and a Sanyo-Denki San Ace 80x80x15 pushing from the other side, like a pair of headphones on either side of the NB.
This combo has the NB temp (idle) down to 61Â°, but I'm not convinced the Papst is contributing anything to the equation. Previously, I had the Papst by itself pushing air through the NB, and the NB temps were still in the 67Â° range. When the San Ace arrived, I put it where the Papst had been (in the 'push' side position) and switched the Papst over the to 'pull' side. My next experiment will be to remove the Papst to see if the San Ace maintains those marginally improved temps by itself.
The loudest component of the whole system, by far, is the stock Sapphire Radeon HD 5850 video card. It's not terrible
, but if it wasn't there, I don't think I would be able to hear anything else at all
. I can't hear anything else over
I think everything else is pretty quiet, but I can't turn the PC on without the video card, and the video card is like a 1967 big-block Corvette with sidepipes at an electric car convention, i.e., I can't hear anything else. I really like old Corvettes (and muscle cars of all kinds), but I don't want my computer to sound like one...
When the MK-13 is available early next month, I'll try to fix that video card noise problem. Then I should be able to better isolate where any other noise is coming from.
