O11 XL Rear Fan

Hudzy · 21 Jul 2021 at 15:08

I'm trying to decide whether or not to fill the rear fan slot on the O11 XL in a triple radiator setup. The side and bottom radiators are intakes, the top radiator is exhaust.

CPU and GPU are watercooled.

On the one hand, it could exhaust more hot air and lower temperatures of the non-watercooled components. Mostly thinking of the RAM and VRM temperatures, maybe the NVME?

On the other hand, it might compete with the top back radiator fan, not actually lower the case temperature, and actually reduce the effectiveness of the top radiator.

Anybody experimented with this?

I have a 60mm radiator up top and it doesn't interfere. Both my rads exhaust, so it probably isn't adding much but I'd prefer to look at an RGB fan than a blank grill

Looks good definitely. Is that a custom front panel?

thanks, yeah that's the coldzero mod giving me 3 fans at the front intake

Ive just added a rear fan for the very reason of its better than the blank grill and every little helps right?
I have the bottom as intake the side as intake and the top as exhaust on 2 x 30mm rads (top & Bottom) and a 60mm rad in the side.

What fans are you using for intake at the front?

All the fans in my case are EK-Vardar X3M 120ER D-RGB. They're all connected to a single PWM controller, I've been meaning to move the front 3 to a new one so they can spin faster than the radiator fans but overall the system run pretty cool as is
