Ok I recently bought a gtx680 but its getting quite warm in games at around 77 degrees.

Its a KFA2 with the reference blower style cooler http://www.overclockers.co.uk/showproduct.php?prodid=GX-006-KF

Its in my Fractal R3 with airflow as shown below (2 x 120 fractal silent in the front and 1 at the back. 2 in 1 out)

Will my card benefit from an extra 120mm fan at the bottom of the case blowing air upwards on to the card or will this just disrupt the fan on the card and cause issues?


Cheers
 
What speed is the fan running on the gfx card?

Could change the front fans to the GT 5400rpms and Put them on a fan controller :-p.

Is the R3 as quiet as it makes out to be?
 
fan runs at 50% under load, Ive removed the unused hard drive trays now and thats dropped the temps by 4 degrees on the card xD

Ive ordered 2 more 120mm fans, one for an intake at the bottom and one for exhaust out the top.


Yes they are as quiet as they are made out to be. with everything at idle I cant hear anything from it and only know its on because the light is on the front :D

under load its about as noisy as most systems at idle :D The gellid tranquillo helps with keeping that noise down :)
 
The fractal fans are brilliant for quiet cooling, but useless for extreme cooling. When theyre at full speed I can hardly feel any wind at all through the hdd cage.

but the R3 is lovely and quiet at idle, WD caviar black is barely audible ( i've read theyre quite loud relatively) I'd say about 40% quieter than my old case without damping :D
 
Despite the side vents at the front, that door severely limits airflow. Have the same problem with my case (Lian Li B25) so I always leave the door open.

TBH opening the door makes little difference :p there is ~12 rpm difference on the intake fans with the door open. The case has a large opening underneath the door too which would probably equate to one side vent as there are no lats in the way.
I just cant wait to be able to afford some of these as im fast getting a build up of dust with this 'very low pressure' set up :eek:

77 isn't particularly an issue, but yes faster fans and a top mount exhaust will improve things

I know its not dangerously high or anything, was just a bit of a shock going from x-fire 6950s (non ref) both maxing under load at 50-60 to 77 with a single card :D

But the new fans will be here tomorrow so hopefully the bottom intake will help push some air thru the 680 and keep it down. Hopefully below 70 and I would be happy with that :)

The fan RPM isn't the main reason why cooling is poor. The case is just starved of air because of the whole front fascia. Getting Akasa Vipers kinda defeats the whole point of the case because they are so loud and even with the sound proofing, the case will no longer be quiet. The best combination of cooling and noise would be to have a case with an open front (no doors) but low RPM fans. That way there's less restricting airflow and the fans can work to their full potential.
 
Got one of these cases myself, and well, it's no longer really quiet :(

I wanted quiet, but I also wanted good cooling. Didn't occur to me that a more "open" case would probably have been quieter as could have used lower speed fans.

Anyway, it's not horribly noisy, but it is not silent by any means.

I have two spectre pro's as intakes, one bottom mounted Sharkoon power 140mm fan, I think capable of 100CFM running at full pelt (susprisingly quiet), one fractal 120mm rear exhaust and 2 fractal 140mm top exhaust, plus 140mm Prolimatech Vortex Aluminium beast on the side.

Silence has gone out the window, but like I said, it's not unpleasant, and it does cool very well now :)

Don't worry too much about adding new fans. Just get something like the fractals which are quiet when run at full speed, just to get a bit better air flow.

I found a similair issue when switching to a Bitfenix shinobi XL, no door and a closed front fascia. Gpu temps have increased by a few c compared to my Lian Li A70F, it has a more open front panel which allowed for excellent air intake.

Cases side by side.

Yeah, fan rpm does equate to more airflow (comparing the same fans) :confused: but the fans aren't good enough to be starved of air in the first place!

I turn the fans off when not gaming anyway, so the noise wont be tooooo bad, I might get these instead though, they seem the best compromise for airflow/noise :D
 
I use a fractal design case, and i had to replace the front fan early on as the airflow wasn't very directed, it pretty much just pushed air into the sides of the case rather than across the components. They are lovely and quiet but I wouldn't recommend them.
 
I have the Coolermaster Silencio which is of similar ilk. My KFA2 GTX570 with bells and whistles on hits about 78 during gaming. I disabled the front two intake fans whcih made little or no difference as far as I could see. To be honest I wouldn't worry about that temp at all unless the temp thresholds are lower on the 6 series?

Ive put the extra fans in now and its made sod all difference to the gfx temps lol.

I had read the 6 series throttled back the clocks when it hits 70, but checking in afterburner says different. So did some more reading and it seems 70-80 is fine for reference cards so will leave it as it is, the extra fans can stay in tho as they obviously help with the rest of the system cooling and they are still pretty silent
