Arc Midi R2 - Fan directions, with water cooling - Intakes and Exhaust

post #1 of 5
Thread Starter 


So I ripped this picture off the internet and included my fans/cooling setup.

As you can see, most of the fans are setup as an Intake. I want the ABSOLUTE best cooling performance. Most fans are upgraded and some of the best on the market, the only ones that are questionable are the stock fans that came with the case, and the NZXT 140mm fan.

What would you guys do in my situation?

So far here are my temps

CPU -

29-32c on second hottest core - IDLE

65-70c on second hottest core - LOAD with Prime95

GPU -

31-33c - IDLE

60-65 - LOAD with Crysis 3 or Heaven

Second picture is screen shot of my setup with overclocking/voltage, ect ect






What do you guys think?

Only a couple of things I can think of that MIGHT help.
* Remove unused PCI slot covers and see if air exhausts through them. With as many intake fans as you have there's a good chance it will help exhaust heated GPU exhaust air. .
* Raise the case up with some 30mm blocks under the feet and see if that helps airflow to bottom fans (PSU & case fan).

Reason is now there is less area for fans to pull air in.. less thn the area of fan itself. 2x 140mm fans have an area of 307 sq cm. With stock feet and 2 fans there is 150 sq cm of area for fans to pull air from.

My case is set up off the floor, on a wooden desk, so that little 120mm fan should have enough air to move, but I'll try it out. I'm more concerned about the CPU temps. Yes it's o/c to 4.3ghz @ 1.2 but 70 is a little high.

I would flip the rad so it is intaking cold air from the outside of the case. Then flip the rear fan so it is an exhaust. That way you will have a nice positive pressure setup with all intakes on dust filters and should have very good cooling performance.

You say "Case is set on desk" that means it only has a space of 20mm or less between the desktop and the bottom of case. I'm suggesting 40-50mm between desktop and bottom of case... and "that little 120mm fan" is sharing on side with your 120-140mm intake fan on PSU for air on one side.. so no air can be drawn into fans in that area. wink.gif

It's your case so it's your decision. I just make suggestions. thumb.gif
