Problematic Airflow with GTX 590

[Cyanide89]

This is my general PC setup, with my GTX590 in my HAF-X case.

I'm having a problem with the airflow. The front fan takes in cool air, but directly above it the GTX 590 is shooting hot air right back out the front of the case. I don't have that plastic duct in there anymore because it drew the air from the front and pushed it right against the exhaust current of the card. The HX750W is gone too... I have an AX850W now, so the fans don't spin unless it's under extremely high load.

I also have the side fan blowing on the card, which does a world of difference (roughly 8-12 degrees Celcius), but what I would like to know is if putting an exhaust fan in the front blowing out through the drive bays would be beneficial to the airflow in the case. I would create some kind of duct that would suck the heat right from the card to avoid disrupting the front intake. Or would that not make a difference.

I don't want to have too positive or too negative case pressure. Please help.

:/ do you pay an air bill? okay thanks bro now that we have that settled here's what you need to do

- Flip your power supply (Fan bottom) *Fresh Air*

- Use a Pull configuration with your H100 *Fresh Air*

everything else is fine, I would've gone 2 120's in the front because 2 of those push more than a 240

what's up with your power 8 pin too lol? did it not fit through the back

Woops, guess I forgot to mention that this is a really OLD picture of my first test assembly for this build. I put the EATX12v cable around back, cleaned up the wiring, and got a different power supply with sleeved cables.

Anyways, I don't need to flip the PSU because, like I said, the fan is never on. It only turns on when I boot up my PC. The load is never high enough.

And would a pull configuration be beneficial to my GPU and other components? Isn't that going to make it warmer? What do I do about the GPU blowing hot air at the front intake?

Also, what's with the air bill comment?

What about something like this, Asus do a better one but I can't remember what it's called.

I'm more concerned about disrupted airflow currents due to the GTX590 blowing out both ends. I just want to adjust the fans to flow properly.

Do you think this would work?

 

[SieB]

Looks like it will work to me.

What I was thinking with spot fan though is you could use it to help push the warm air from the back of the card strait out the front outake, it would also be sucking the cool air from the front intake and blowing it over the card and out the front outake.

 

[Cyanide89]

Guess it can't hurt to try.

I didn't think you could get a H100 in the roof of a haf-x (how did you do that) also i would say that the air flow is not a problem an less the temps go up alot on the gpu in which case i would just slow down the front fan untill i got good temps (always have the front fan as an intake) i hope this is of some help to you

The HAFX has room for a 360 rad... the H100 fits perfectly with room to spare, even in push-pull configurations.

I attempted this airflow setup:

Now my idle temps are below 30 Celsius for my CPU and 35 for GPU. Maxing 45 for my CPU and 60 GPU.

I think it's working nicely.

Very nice, looks like the new config worked a treat!

 

[Jadarite]

Bang go's the theory, if it works it works

 

[Cyanide89]

Except one issue. AIDA64 is reporting all component temperatures except my Crucial SSD. It isn't listed for some reason.

Why is that?

 

[PetrolHead247]

Download HW monitor and see if that reports the Crucial drive, but i wouldn't worry about it tbh

 

[Cyanide89]

Yeah, it's listed under devices but just no temps. Thanks though.

 

[PetrolHead247]

Ah no worries then, most likely AIDA64 just being a bit buggy and not showing temps
