C70 side window fans

[App4that]

I just installed a crossfire configuration in my C70 and would like to further improve the ventilation. I've replaced the stock side window with the holes for a fan with a laser cut replacement without the holes for aesthetics. Thinking of going back to the stock window so I can throw a couple fans in it. Anyone using fans in the window, or heard of someone doing so? If so how well does it work?

I have four intakes in mine:  140mm/140mm in the bottom (all cages are removed), and the two stock 120mm in the front.  I know you want direct air being blown right at the GPUs, but if you can remove at least the one HDD cage, you can get a lot of fresh air in.

 

If that does not work, then jam the old window on with a fan for the GPUs.

I currently have 8 case fans, all 120's. 5 intake, two in the front, two in the bottom, and one on the top cage (bottom removed). I have 3 exhaust, 2 on the top pushing through the CPU radiator and on in the top back. The intake on the front without the cage, and the rear on the top back are both high flow verses the static pressure of the rest.

 

Only concern I have is after an hour of bench testing in Valley with cross fire enabled I reached 50c in the case, none of the components went past 80c though. So my thought was to throw the fans in the window in an exhaust configuration.

You can fit four 140mm fans in this thing (I forgot you have a rad, so two for you)... if you find good prices, that could be an option.  I got my Bitfenix Spectres for $8 each (CDN).  They are not the greatest, but they do their job.

 

Well, you are capable... if you have to test with more exhausts... best of luck!

I think you have plenty of airflow already tbh lol. 50c for a gpu is nothing.

It was case temp... so I assume he has thermometers in the case... but I should not assume.

Ah I misread, still none of his components hit 80c so I'd still say everything is fine. If he left a loop of valley on for an hour then that case is going to get nice and toasty.

I should have been more clear, my fault. I have a fan controller that has thermometers in the case so I can see the temperatures in the case. The highest is almost always right off the back of the top GPU. Not in contact with the back plate but attached to the power cable. I hit 43c tops when gaming without crossfire enabled. Unfortunately I don't have anything that requires enabling crossfire so as to know the temperature when gaming, but Firestike is almost ten degrees cooler for all temperatures in comparison to Valley so I assume that is a good representation.

Honestly I really doubt you would see temps dropping worth all the effort of rebalancing your positive pressure etc.

I had the same feeling but tried putting the shit fans that came with my H105 in the window, holy shit did it work. Case temps fell from 50c after stress testing with Valley to 41c, highest temp while testing with Firestrike was 37c. While playing witcher 3 with everything maxed except Hairworks I hit 35c in the case. GPU's run a few degrees cooler while stress testing but for some reason I gained 400 points in Valley and 630 points in Firestike, and I had just checked last night so it's not the drivers. The 390 played at ultra settings in Witcher 3 on it's own and never fell bellow 30fps, worse dips were in the very high 30s, with crossfire enabled (after jumping through hoops to get it to work) I'm pegged at the 60fps I have it set to and both GPU share the load and never cross the mid 60's for temps. 

 

So guess who's going to be picking up 4 new fans tomorrow from Fry's? THIS guy! :lol:  Only way I can fix the ugly with having those fans stuck in the window is with LED I think, but I am pretty buzzed, PC fiddling and alcohol = more LED's :lol:

 

OH! And the problem with my CPU running hotter than normal, totally gone. Happy day!

...and people made fun of me for running 7+ fans in my cases... pfff.

A temp drop like that is probably down to ambients being lower or those fans are blowing onto the motherboard sensors, if not those then I'd put my money on your case not having balanced airflow with a dead spot next to the gpus. Personally I want to bet on the ambients.

I have to admit this experience has made me a, fan, of the idea. *snicker, snort*

I have the good fortune of have a wall mounted thermometer right next to my desk, the ugly is real but so is the information it offers, Ambient is the same as the last few days, right around 25c.

Must of been a deadspot then, surely those fans blowing the same temperature of ambient air onto your motherboard etc must be the cause.
