Cooling, PSU flip?

Hey all,

Ive got a ThermalTake Tsunami tower chassis,

except that I replaced the front fan and side fan with faster ones and I have an MGE power supply in it:

Right now my system idles at 30c, and under load it can go up to 45c. I'm trying to lower that temperature as much as I can.

As you can see I have 1 12cm input, 1 9cm input, 1 12cm output, and the 12cm and 9cm fans on the psu.

I read an article online where by flipping the PSU and setting up that PSU fan to take air from the top of the case, they were able to increase cooling. My question is, Ive got TWO fans on MY psu. Are those messing up my airflow? What do I need to do to increase the cooling in my computer?

Ideally, you should have your power supply exhaust air out the back - you have two, so the outside one should blow out, and the inside one should draw in (to the power supply).  The reason is the power supply generates heat, and you don't want that heat to be pushed into the case.  The other principle is creating airflow: you need a balance of fans that draw air in and blow it out.  The lower front is a good place for drawing air in, since the power supply is going to blow it out from the top rear.  Have an equal number (or equal total CFM) for in versus out.  I also recommend an exhaust fan right next to the cpu, because that is a big heat source in which you want to get rid of the hot air as soon as possible.

A couple of points from your photos:

1) Tidy up your wires! Aim for something like this
2) Fold up those IDE cables, or get some rounded ones.
3) For ultimate air goodness, get a holesaw and drill a 120mm blowhole in the top and get a nice big fan in there.
4) It looks like you are using a stock heatsink. Whilst adequate there are higher performing ones out there like these:

Good luck!
