I have made a new video depicting what it would sound like with the push fan plugged in only and vice versa (pull fan plugged in only):
The optical dvd-rw drive, hard drive, other case fans, and pump are still plugged in.
It seems they are both on equal loudness with the pull fan being slightly louder. This may be because that front is on the front and more audible to the camera/myself.
The basis for my comparison in loudness is that:
1) The fans/setup is MUCH louder than my original stock HSF combination that came with my i7 CPU. I thought this would be quieter. :-(
2) From other users with H50 + 2x AP-15, it seems they're getting a "remarkably quieter" setup. They have compared it with me personally and says mine sound loud for some odd reason.
Also, both those two fans are connected to the mobo's 3-pin connectors. In the BIOS, it shows one fan running around 1780 rpm and the other fan around 1750 rpm. I believe the AP-15s are rated at a max of 1850 rpm, so it looks like they're running at about 90% speed right now.
What do you guys think? The fans sound normal or not? I am going to try testing my temps with Prime95. I'll try testing what my temps are at stock versus overclocked (I'm hoping to get at least 3.6-3.8 GHz with my setup). Hopefully, my H50 and it's setup is OK... but it seems others are getting better results. *sigh*
