My front intake fan is on 100% although a temperature monitor says that my CPU is only at 25 degrees C. I just swapped the power supply with a larger one so I could put a new graphics card in, what could the problem be? maybe I need to put more thermal compund on the CPU, since I had to remove the heatsink to run the wires through.
Anyhow, quick replies would be appreciated. I'm afraid my comp will die, it currently sounds like a jet.

The PSU is an OCZ gamexstream 700w, it was a decent fit and seemed to be compatible. The computer itself ran fine apart from the fan, I don't believe that the CPU was hot at all as I checked the temperature on CPU-ID and it said core temps ranging from 23- 27 degrees. Seriously though, it was scary how fast the thing was running....
The system is standard Q6600 2.4, Geforce 9800GT, 4GB Ram. I bought such a high powered PSU because I was going to upgrade to a 4870 x2 graphics card and Q9650 3.0ghz.
I have also just replaced my Dell PSU with a more powerful one like you. My new one was a Coolermaster 700W Silent Pro. Although I've had no problems with my processor fan running fast with the new PSU.
Unlike you though, I just pulled the wires past the heatsink shroud without first removing it. Maybe in removing the heatsink shroud you changed something or unseated something? I would take a closer look at it to make sure you haven't done something to it which would make the front fan run so fast.
Also, have you made sure that all the power cables have been correctly set with the new PSU. I know there are two cables which have to be pushed into the motherboard. I think they're one 24 pin and one 4 pin cable. Also make sure all the other power cables are securely fastened. I think I had to run two sata ones to my two Hard-drives, one six-pin to my Graphics Card and one to my sata DVD-drive.
Hope you manage to fix the problem, Paul
I don't think anything was unseated, I checked everything numerous times, the system went back to normal with the Dell PSU back in so I'm assuming that the PSU is either incompatible or faulty. From memory the wires I connected were:
24 pin (but this was a 20 pin + 4 pin extension)
4 pin to motherboard
6 pin to graphics card
1 x SATA to hard drive
2 x SATA to DVD drives
1 x molex to case fan
I checked it against the Dell PSU and all cables were present. As I mentioned, the computer functioned perfectly aside from the fan. Checking in a temperature- monitoring program showed my core temps to be around 25 degrees, so nothing to worry about there.
I'm looking into a PSU upgrade as well for my 420. From my research, the only that is a shoe in is the Silencer 500W. It should juice a 9800 GX2 from my math. That would let all the other top end GPU's even GTX280 into the frey. Disclaimer: Accurate numbers not in as definite for Q97xx (or QX) Cpu's or QX9650 and sketchy info on the HD4870X2 or with extra cage fans or Retail fan/heatsinks if you can find one. As for the CPU fan/heatsink... PM me if you find a fit PPLLEEAASSEE. I also only have one HDD and run the others USB but rarely for data backup/copy, rarely use the optical drives and shut down programs to run Stuff to my HDTV.
Sometimes the 20 vs 24 plug can be iffy.
Just an update:
I fitted the ANTEC Earthwatts 650 as advised by forum members and it solved the problem. Looks like the OCZ power supply was faulty.
