I worked on Z10 IBM Server Racks and I can tell you this. Exhaust fan always faster then the Intake for best performance. This is not a cute PC tower. Cool that thing like a Server. So try it out. Here the outcomes!
Stock fan intake with Mickey Mouse 1000 rpm fan as exhaust= Fast fan goes to 2-3000 rpm 1000 rpm fan can keep up and gets speed up by stronger air flow. There we have back-pressure and heat stays longer in place + pressure resistance for the faster fan. Just give it a shot and try it out. Use a external thermometer for the measurements.
2 the same fans can work great but on the long run the exhaust will work harder due to Pressure turbulence from the first fan (thats why ships have there propeller offset.) Due to previews sentence is the Lifespan of the fan lower, when the exhaust slows down due to that fact you will have the same issue in example 1
So I am new to the Bitcoin world but I needed to tell Business owners that they need a new rack due to overheating caused by a know it all programmer (I can't programmXD btw) replacing a exhaust fan what looks like the oem fan but was a 2000 instead a 4000 inside a closed IBM Z10 Paraboard Server Housing. The replacement cost $24.000 (that's the insurgence price. So you guys teach me overclocking stuff and I help u to keep ur Hardware alive
ohhh I like the heatsink idea btw. Notice to at the first pictures that he aligned the fins towards the flow. I seen some nutcases putting them up.
I received my s1 in the mail couple days ago. Still run the stock fan no OC work don't to it. I have the German designed Cougar fans as well but they blow from the side in a 45 degree angle from the main fan side aganst the blades. I ordered some Alu heat sinks (cooper is better but heavier as well and i dont trust the thermal glue stuff that much.) My future setup (in the next 3 weeks) is 2 Delta Fan's (they are very LOUD!!!). 2 the same fans but intake speed reduced by 25% where the Exhaust is hauling full power.
That will be a 60 dBA Setup but its the best cooling u can get (besides water or liquid nitrogen XD)
So don't put that in your bedroom.
