Yes, I personally find it amusing to have the only RGB in my entire case below the gpu in the back of the case. That was on purpose.

They make 70 and 60mm fans, too, if it's just a bit too big. Noctua has a 60mm fan, but not 70. Couldn't find an arctic fan in either size.I'm tempted to order 2 40mm fans and mount them to the left where a normal person would mount a resivour.
A 80mm was just a touch too wide.
Wonder if I could sand down the edges...
Then I'll try the cardboard duct idea you guys had for fun

I know that I'm resurrecting a 2 year old thread, but it occurred to me when building in my new Fractal Define 7 XL that I could actually fit a 120mm fan underneath my GPU if I move the GPU to the top slot. A regular 120mm fan was a bit too thick but a slim 120mm (Scythe Kaze Flex Slim RGB) fan fit perfectly.
It had a small effect on my load GPU temps - they're a little slower to rise but the overall temp only went down about 3c, but it had a huge effect on my CPU temp, -5c during a game with gpu load. Probably because the heat from the gpu is being sucked out the back of the case instead of just recirculating inside the case to slowly rise through the CPU heatsink. The only NVME drive that had a noticeable temp decrease was the one on the riser card, probably because its directly in the airflow. The three motherboard based nvme's didn't change temps at all but that's probably due to the giant heatsink plate without any fins. Chipset temp is also basically identical, I think the 120mm fan is too far away to help with that.
Overall for something that took about a minute to install and test it was a worthwhile test and I'll likely keep it installed until I fill the lower PCI-E slots.
I uhh, forgot to get side pics before I tested, but I'll probably snap some later. It's impossible to see inside my case during its normal operation.

But here's a pic from the front, through one of my intake case fans. I think it shows perfectly how well it just slots underneath the GPU. I don't even have it mounted or tied down by anything, friction keeps it in place perfectly.

molex? if so you can run them at 5v by swapping the red and yellow wires on the molex plug they go into. only do it with the last plug at the end of the psu cable though. if theres more in the chain the voltage is reversed until the end plug.added 2 80mm just to the left of the gpu as additional exhaust. Made them fit.
They're super, super open in this case. Given how often that I'm blindly digging at the rear of my case for plugging my GPU in, I figured it was better for my fingers to just leave them in.Are you removing all those pci case slots behind that lower fan?
Define 7 XL. It's a monster. I love it.Interesting what case is that? In my Fractal Design Define C, the slots are solid with no airholes
now try the fan as an intake, instead of an exhaust. I bet you see even better temps.Not a fancy test, just my anecdotal results.
To me, the heat produced by the GPU, being forced down, back into the case, instead of forced out the back is a general source of unnecessary heat.
So, I had a spare Arctic F9 92mm fan and placed it at the rear of my case, directly under the 1080ti.
The idea being to exhaust (some) of the hot air out of the back of the case.
The 92mm fan wedged perfectly under my EVGA 1080ti SC2 and the bottom of my Phanteks Enthoo Pro M.
Supposedly the little fan moves 42cu ft of air, and it certainly is impressive for how small it is.
Preliminary testing showed a 5 degree drop with my GPU fans at 25% and 3 degree drop with fans at 60%. This was with a +99core and +500 memory overclock, on a heavy (gasp) mining workload.
Is this earthshattering? No.
But it's enough of a difference for me to leave it in there.
It also might allow to drop the GPU fan rpms a bit, to decrease the noise. The Arctic F9 92mm is virtually silent.
The won't work if you want to populate the other pci slots, obviously.
It also might help with GPU sag

it will make the gpu run cooler as its getting fresh air but it would also help puch hotter air from the gpu to the top of the case. if you have good front to back/top airflow the difference is minimal, a couple C. its what ive been doing for years. until i went gpu aio and now with my 5700(no aio) which doesnt seem to need it.I think I read that gpu at that location as an intake actually adds heat
If you can word it better, please do.holy run on sentences batman
If you can word it better, please do.
So you put down my helpful but according to you poorly written posts with nothing but incomplete derogatory comments. Sure shows your true colorsboy i'm not doing your homework for you
