Recently purchased an AIO cpu cooler, coolermaster 240. Have 3 system fans already all 140mm, phantek fans.

Case is: https://www.overclockers.co.uk/phan...black-full-acrylic-side-window-ca-040-pt.html

Gpu is sapphire Nitro+ rx480 8gig.

Torn between:

Radiator at front with fans set to intake, 1x140mm top exhaust and 1x140mm top rear exhaust - both set to lowish rpm.

Or

Radiator at top as exhaust, 1x140mm top rear exhaust and 2x140mm front intake.

Would I see much higher difference between the 2 configs? Or is it just going to be personal preference.

Read that it's best to aim for slightly positive pressure but also read that negative is better for cooling.
PC is kept on a short thread carpet floor in a low dust room.
 
Yes, saw that video during my research, also one from 'jayztwocents' where he argues for front mounting.

Just still see so many mounting at top.. Think best way would be to try front and do temp tests then later switch to top and play with fan setup.

Was just hoping on some feedback as not very mobile at moment as had tibial IM rod removed but to impatient to wait until fully healed :P

Cheers for reply :)
 
Did a front install as intake with 1x140mm at top exhaust and 1x140mm top back exhaust.

Stuck a quick o/c of 3.8 @ 1.389vcore and went to run OCCT. Cpu never went over 68 but something hit 85 and the program auto ended.

Need to have a closer look at it all, I always question installation as I find them fiddly as heck! Also pump fan rpm was showing at 2980 while cpu is at 780 all while idle.

Thinking with my case and mobo (b350 tomahawk) top mount as exhaust might be better with 2x140mm front intake and 140mm top back exhaust.

Had to break off for dinner so will play with it tonight/tomorrow.

moved radiator to top, these temps seem decent to me - considering I've got vcore quite high at moment.

Pump is plugged into pump fan on MB which is always at 100%, radiator fans are in cpu fan on MB, wondering if I should do an auto tune with MSI command centre or not?
