Radiator giving off a lot of hot air. How can i reduce this?

Hi, I have an overclocked i7 (3.9ghz) and 2 5850s on a waterloop with a black ice gtx triple radiator.

I have it mounted at the top of the case internally, with 3 gentle typhoon fans drawing in air from the top (outside). I have not put an exhaust fan on the back (I probably should :rolleyes:

)

Now... The air inside the case is really quite hot. From the radiator. I have the side off at the moment or it would overheat in there. This heat makes the room very hot so the water struggles to keep kwl. I have got the window open!!

Here is the question...
What should i do, I can put a 140mm exhaust on the haf (either included 140mm from coolermaster or another). That will still make the room very hot.

Well drawing air in through the top pulling cool air in to cool the rad... heating the air up, and dumping it in the case.

Surely you should have the fans blowing the other way? Pushing air out of the case to vent the heat from the radiator with some intake fans pulling cool air into the case elsewhere?

At the least, if you continue drawing cool air in from the top of the case you should have some venting fans blowing the hot air out.

The HAF932 moves a lot of air, the side panel fan alone blowing out would help removing the hot air but I am not sure that is the way to go.

Generally its best to have front to back, or bottom to top as a basic design.

Pushing air in from the top is silly, hot air rises, why try and fight it? Have it sucking air out, and put an exhaust fan on.

ok ill change it round. I was told to do it this way to have cool air coming in from above.

With you water cooling setup you have all the heat generating components in the loop so shouldn't be much heat dump in the case.. I would use the rad as an exhaust with the front and rear case fans as intakes.

Because the bay res is in the way i will have to find a screw driver with a short handle. DOH!
