i5 Temperature while Gaming

Now if you want to replace heatsink compound and make sure everything is clean and spinning then do that but it's still not where I'd worry.

A person here posted claiming that their Desktop heated the room so hot that it was not possible to stay in it using the computer. Not something I've ever run across but I gave him the same advice look at the actual Temp of the CPU and GPU in their case and make sure that they do not get much over 100C but they were talking for longer than 24 hours of consistent high use.

As things stand the more you use the CPU the hotter it's going to get or at least the more load you put onto it the hotter it's going to get the real test is if once you stop look at what the CPU Temp is doing. If it stays hot then something needs doing but if it drops back to above ambient then it's all fine. It's never going to reach room Temp as you need a lower temp on the cooling air to cool the heatsink so anything up to a couple of Degree's C above room temp when it is not being used is fine. You only really have to worry with Intel CPU's when they start getting up to Temps were the Silicon starts to melt which is way too hot but can happen went Overclocked to the extreme.

Pity that all the electricity they use doesn't help heat the room here at all as if it did the i7 currently beside me would help warm up the room quite nicely but it doesn't and I have to wear jumpers in winter and rely on Air Conditioning in Summer. Here it gets so hot that some components on the Motherboard reach their Max Working Temp before the things gets turned on and we regularly see temps in excess of 35C daytime AirTemps and that doesn't hurt this thing one little bit. Of course when editing Video or pictures it gets considerably hotter but for general Office Work it's not an issue.

I also bung as many fans as possible into cases because Air Flow is difficult and easily disrupted so it is possible that areas inside the case can get much hotter than others more so if you had IED or Floppy Drives with those Wide Ribbon Cables which blocked air a lot but not anywhere as common now with SATA Leads.

But just for your own personal knowledge the fans suck air in at the front of the case and **** it out the rear just do not place the case in a position where the case is loosely sealed in a alcove and the only escape for exhausted air is up the side of the case where it gets sucked in at the front. I've seen some "Modern" Computer work benches have a problem as they have a box all but enclosed where the case fits and there isn't enough room for free airflow around them between the case and the alcove.
