You can hold the pull fan a distance away from the rad and as you move it closer the buzzing starts and gets louder until the fan is against the rad. It can't be any contact because it was happening with a clear 5mm gap between fan and rad. Maybe if the gasket was like 10mm thick it might make a difference. However I'm not sure that the gap is not reducing noise just because the air can escape from the sides, maybe if that gap was filled the problem might still be there.

I wanted to replace all my corsair fans with eloops but bought 4 B12-3's and was disappointed by them. They are great in push only but that is all it seems.
The sound on this sin't great because it was done with my phone. You can hear the sound change as I plug and unplug the pull fan if you turn it right up.

Just curious, but did you try to run the fans that are in push at a lower RPM than the ones on pull? Does this happen if you have the fans only in pull configuration?

It seems to me the pressure from the push fans are screwing with the weighting of the blades on the fans in pull causing issues with the motor/bearing. I would think giving the pull fans an edge in power will allow the motor to more smoothly rotate the blades.

That's one thing I love about the GT's--the blades are heavy/thick but still perfectly balanced. If you spin one with your finger it'll go for a good 20-30 seconds before smoothly coming to a stop. Other fans have less weight to their blades and often come to a jerky stop when spinning down.

I've had to send mine back, great design very poor build quality in comparison to a corsair c70.. almost feels too delicate that it will break with one small mistake

It actually becomes much more rigid once you have your gear in it. I thought the same thing when I first pulled it out of the box.

Again, surprised by how long the blades kept spinning after power was cut to the fans.

im going to reorder another as this one had scratches on one panel plus the panel without the window was bowed out slightly towards the top, so it looks like it was bulging out

I really do like this case & really thinking hard on what watercooling setup I could do inside it..

I already have a 360mm rad, looking for maybe a 280mm next or 240mm.. but thinking mostly on what pump & configuration redface.gif

My cables PCI.E

post #3417 of 9555
Just got My 750D to replace my dust magnet, HAF922, and after building 2 PC for others in the same case I was excited!
But there were a couple problems with the case.
First was that the window panel screws were completely missing, but later found them rolling in the case.
After getting everything installed, I noticed that in the back, one of the feet were severely cracked from what appeared to be over-tightening and a hard hit to that same corner during shipping. (The Box's foam was also split) Warning: Spoiler! (Click to show)
I also noticed that the drive sleds had left shallow scratches from where they had made contact with the side panel window, with no internal plastic sheet for protection. So that was a bit disappointing, despite my previous builds in the 750D.
So I will be contacting Corsair soon to see if i can get a replacement for the back feet

Otherwise, the 750D looks fine, no broken clips, dents or warping and everything is much cleaner than before and running as it should~
I'll post more pics once i find my camera.

^ We'll get that sorted out for you. Have you submitted a ticket yet regarding that feet? If you have, PM me the ticket # I'll speed things up so you can get a replacement right away.
