Newegg had the Corsair H50 (quiet edition) for $25 after MIR, so I pulled the trigger on one.
I was previously using a Xigmatek HDT
120mm tower cooler with a single push fan in my Silverstone PS07
(same as TJ08 but different front panel) and a 120mm fan exhaust out the back of the case. Because this case is so small, having a liquid cooler is beneficial for opening up work area inside.
I installed the H50 with an Enermax DF Pressure
on the push side, but noticed during my first stress test that, despite the fan being rated for high static pressure, there was a LOT of air "splash-back" and I couldn't feel any noticeable air movement out the back side of the radiator. This is concerning because the radiator exhaust is the only forced air exhaust in my case, so I worry that although the CPU stays cool enough during a stress test, that the waste heat from my GPU will have nowhere to go. Next, I added an Enermax TB Silence PWM
on the pull side thinking that the perforated frame would reduce the fan/motor noise of a "pressure lock" between the dense fins of the radiator and the intake of that fan with the added benefit of sucking air out of the case that isn't necessarily passing through the radiator.
I've got the airflow I'm looking for, but I'm not satisfied with the noise profile. One of the main problems is that both fans are PWM so both ramp up as CPU temps increase. The other is that I haven't gained a single degree of temp drop from my tower cooler, to one AIO fan, to two AIO fans. Very frustrating. I have a number of other fans I can try (stock H50 fan, Cougar Vortex PWM, and a number of other random fans I've bought because they were on good sales) but I don't have a lot of time to dedicate to changing out fans, testing, new fan, retest, etc etc. Does anyone have any recommendations as far as what I should use/try to expedite this process?
