New PSU, pc case overheating

May 6, 2009 at 15:33:13
Specs: Windows XP Pro SP3
I just installed a new Corsair PSU. Everything was fine only I'm on the second day of use now and the fan is going like crazy and my pc case is physically hot! I've connected the 2x connectors to the mobo, and the other new connectors for the sata cables. Could I have added the pcie-type one to the mobo wrong? I have a Corsair 450vx PSU, Gigabyte s-series mobo ga-g31mf-s2. 2gb DDR II, 160gb Sata HDD. The PSU fan is plugged in and both fans are going like crazy. Please help.

"I've connected the 2x connectors to the mobo"

What do you mean by that? The 24-pin main ATX plug & the 4-pin ATX12V plug?

"Could I have added the pcie-type one to the mobo wrong?"

Again, not sure what you mean. PCIE plugs connect to the video card, not the board. They have either 6 or 8 pins.

"The PSU fan is plugged in and both fans are going like crazy"

Once again, not sure what you're trying to say. There is only ONE PSU fan...a large 120mm fan built in the underside of the unit. And it does not require being plugged in.

Yes

"Could I have added the pcie-type one to the mobo wrong?"

What I mean by PCIE type plug is that it's similar to the one which plugs into the graphics card - I didn't know what it was called (4-pin ATX).

"Once again, not sure what you're trying to say. There is only ONE PSU fan.."

I mean the CPU fan and the PSU fan. Both are running and there's still a lot of heat inside the case. When I leave the side of the case on it gets physically hot at the back.

EDITED: My PSU seems to have a 24pin connector and a 4pin connector for the mobo. I tried leaving out the 4-pin and it wouldn't turn on, so I plugged it back in. Was this the right thing to do? Do I need both. Also, it definitely seems to be 24-pin as it took up the entire slot, I had a 20-ping before which only went in the centre of the slot on the mobo. Hope this is clear.
