Made a quick Excel table just for the fun of it (attached - based on manufacturer values ofc). :mrgreen: I have a hefty stock of Noiseblocker (non-PWM, PL2) case fans already, otherwise I'd just grab both an ~1300 and a ~2000 RPM fan; they are all relatively affordable. I'm thinking I'll just go for...

See if you can find one of the fans we used -- Slip Stream 120 PWM : scythe sy1225sl 12hpvc-v That was my first choice, but for some reason they discontinued this "adjustable rpm" product line. I was able to locate the 140mm variant (SM1425SL12HPVC-V) in stock, but there's no room in there to fit a...

The SY1225HB12M-P may be too slow -- top speed is only ~1300rpm. You really need a >1800rpm fan, ideally one with a speed control so you can slow it down to the point where it doesn't bother you AND doesn't lead to computer shutdown. Thanks Mike. Back to the fan hunting game, then! I guess I should...

Sure enough, the Microserver 54L would shut down after a while as it couldn't detect the fan. Too bad, because the Noiseblocker PL2 was very quiet even at full speed. I'm thinking of ordering a Scythe GlideStream (model SY1225HB12M-P, as reviewed here ). Any objections in terms of the specific appli...

No, it MUST be a pwm fan, otherwise, it will simply run at full speed... and the control circuit might not "see" it and shut the system down. Thanks for the reply. The fan running at full speed would not be much of a problem (I could control it externally), but the system shutting down...now, I can...

Thanks to SPCR and its community for the loads of useful info they provide! I recently got me a Microserver 54L and would like to replace the stock 120mm fan, as its now the main source of noise in my computer room (mechanical keyboard aside :mrgreen: ). I was hoping to use a Noiseblocker PL-2 I hav...
