Improve my Cooling (Pic inside)

[MFrost]

Hi folks,

I'm calling on OcUK to provide some advice on cooling. I have a Corsair 700D and my temps just seem too high. i7 950 hitting 75'c under normal load (currently only overclocked to 3.8) graphics card (gtx480) hitting high 90's.

The inside of the case feels too hot. When i take the side of the case off I get a good 5-10'c off the temps but i'd rather not run it with everything out in the open.

Below I have attempted to make a picture (in paint) of how the cooling currently is:



I'm toying with the idea of changing direction of the CPU cooler and making the rear of the case an intake and letting the top fans exhaust? Good idea/bad idea?

OcUK...fix my cooling! What am i doing wrong here.
Thanks a lot for any advice!

I'm thinking you really need a front or side intake fan and could probably turn off one of the top ones.

I also thought this, but then thought it would be made redundant by the top exhaust fans pulling the air that the front fan has brought into the case straight back out again?

Unless you have deliberately switched the fans round on the Noctua D14 then you have the cooler on backwards with the fan trying to intake air right next to your exhaust fan.

If you have switched them then disregard this.

I did switch them as think i mounted the heatsink around the wrong way and couldnt be bother to take it off and turn it around again .

Thanks

You have one and a half fans intaking (from psu chamber and I count the hd bay one as half as its obstructed.) and six exhausting into the main chamber with that setup. At least trying the DH14 other way round probably couldnt hurt.

Point well taken, i've moved the fans on the DH14 to face the other direction as shown in the new picture.

I think a common option on this case is to swap the right most of the top three fans from outtake to intake. This will blow air down towards the bottom of the case and in theory it should circulate back up.

I did try this, but I couldnt feel any air from the right hand fan at all after about 1/4 of the way down the case...I think the 2 left top fans were sucking the air straight back out again.

Swap the rear exhaust to intake as well, then you will essentially have 2 intakes and 2 exhausts for the main compartment, with the extra intake at the case bottom, which in my opinion is hampered by the design in terms of what cfm you ultimately get with the arrangement of those bottom fans, I suspect given the voids and separation the bottom fans see a large pressure drop and therefore at not as efficient as a normal case fan arrangement.

The bottom intakes are diabolical to be honest...the fans they come with move no air as it is...so trying to push some air through a shed load of cables from the power supply then into the case is almost resulting in no air what so ever.

create possitive air pressure and get the air curculating faster and ther for lowering temprature due to the wind chill off higher speed air movment

I'm not really sure how positive and negative air pressure works in computer cases but i guess you're saying to try and equal intake fans to the outake fans? (e.g. 3 intake, 3 outake)

Anyway here's what I have now...the CPU seems to be quite a bit cooler now (7-10'c cooler in fact)



The graphics card is still in the 90'c to 100'c mark but there doesnt seem to be anything I can do about that - there are just no mounting points for fans at all near that.

Any other suggestions for trying to cool this down some more are very welcome. I seem to be spending more time trying to cool this monster down than actually using it!

I hate to be a tool, but don't buy a Corsair 700d/800d for air cooling? The amount of times I see this discussed on forums and the moral always seems to be to just accept it, or get water cooling. These cases weren't ever built to accel at air cooling really.

I didnt realise to be quite honest, i purchased the 700D because it was big and looks so pretty. I like the simplistic look.

how tidy are your cables? Maybe you got a hella mess inside?

It's almost the opposit, it almost looks as if the computer has no cables, they're all hidden away.

Did a prime 95 while I noshed on my dinner and my CPU is hit a max of 74...which i'm hoping is fairly safe?
