If you can Deep-6 try and upgrade to a better heatsink and fan combo for your CPU. That alonewill help alot to drop temps. Now this will sound dumb but... get a PCI fan and install it it under your graphix card. That will aslo help get ride of more heat. And also a fan for your HDD. Radio Shake has all 3 made by Thermaltake in some of their better stores. I did the above last month and it helped a great deal. I've got 11 fans in my case now. 4 filtered intakes and 7 exhaust.
My Thermaltake v1000A case came with 7 plus 2 in the PSU. With the HDD fan and PCI fan that makes 11.
Now for the hard part..... make sure you have filtered intake fans. They'll keep the crud out which is what you want most of all. The crud and dust sucked into the case is what will make things heat up faster than a cat on a hot tin roof. Pardon the expression but it's true. Never ever, if you can help it, leave the sidecover open. That's only asking for trouble. And to the filters, add the dry dusting cloth cut to fit. I bought a box of Grime Boss Dusting Cloths that I found at Wal-Mart. Works better than the stock fan filters.
This is especally important for all of those that buy those store-bought computers. Check inside the case once a week to see how clean it is. If it looks dirty, take the time to clean it out, and do heatsink with canned air. The fan blades can be cleaned with canned air, but more than likely will need to be scrubbed with a Q-tip too.
Reason I say this is.... my son-in-law hadn't looked insde his computer case for 2 years.
There was so much dust and crud in it that it was a wonder it didn't catch fire. It also ran slower than death warmed over until it was cleaned out. The cleaning alone took over 2 hours. LOL It runs better but the damage was already done.
