Hello, new here. Just have a request for advice....\nI bought a refurbished GT4016 earlier this year from a company called\nTech For Less. I'm very happy with the system in every way except one,\neven though the poor thing looks as if it had been dropped a couple of\ntimes and was scratched up and the plastic broken in a few places. The\nsystem is just fine and much better in many ways than my last system and\nthe price was great, under 0. The problem is the cooling. I don't\nknow enough to know if the system is running cool enough. It currently\nruns like this: CPU = 54-57c idle -58-63c under load, AMD single core =\n34-37c idle - 45-48c under load. (I regularly monitor the temps using\nSpeedfan and AMD assistant and have double checked them using the free\nversion of Everest and MBM.) It's about 75-80F in this room with two\nwindow ACs running. (It's a big room.) The computer is the BTX design\nand has the funnel thing in the front with the intake fan and the power\nsupply has a fan and Tech For Less added a heat sink fan when I first\ngot the computer to help with the heat problems then. (When I first got\nthe system the cpu was idling at 62c!) In the manuals for the system\nthere are photos and all the photos show an exhaust fan on the back\ngrill. Would I mess anything up if I added one? I think I have\nresearch overload. I've been looking this up on Google and reading and\ntrying to find a simple yes or no, but wow there's so much information\nand I just can't figure it all out. Are these temps normal for this pc,\nor would the exhaust fan help it without causing more problems?\nThanks... I hope you guys can help.
