OK,so I have a Dell Precision T3500 with 2 fans installed at the front of the case.And I haven't changed the factory cooler which has a model number of T021F. So at idle I get temperatures of around 25-30 degrees Celsius. I guess that's alright but when I play CS:GO with 720p Max settings, [strike]no MSAA[/strike], I reach 70-80 degrees. I have a fan sitting 10 ish cm next to it. I recently found out the fan stays at 750 rpm at all the time and rarely turns up (found out it's common for all Precision T3500-5500-7500) so I saw a tutorial on YouTube how to set up SpeedFan and it works but its either 750rpm, 1200rpm or even higher when you bump up the percentage to 70%. Then the CPU temps seem to go down by around 5-10 when I run it at 1200rpm (because of noise I don't go any further). My question is why are the temps so high and would it help if I change the thermal paste/compound since it probably hasn't been changed since 2010( year of manufacture)?

I will include some screenshots if anybody needs them to help me.

The T021F is the older sink and not that good unfortunately. Changing to the copper heat pipe model would be great if you can afford it.

As said above. Try cleaning, apply good paste and re-install. Doing that with my T3500 dropped temps significantly.

Changing thermal paste can definitely help if the CPU was seated a long time ago. Since it was initially installed by the manufacturer you can probably get better thermal paste than what is on there now. Also make sure your heatsink is free of dust so that air from the fan can freely flow through it. You could also get a new fan and/or heatsink to put on it (maybe get a silent fan since you are concerned about noise).

As for why it's hot, there could be several reasons. Stock coolers do not cool as well as aftermarket ones. The thermal paste is getting old. Your fan on the heatsink may not be sufficient. If you are running on overclock the CPU will run hotter. That said, 70-80C isn't terrible. I would try to get it cooler, but it shouldn't kill the chip.

I don't really have a lot of money and would be happy to upgrade to the bigger Dell heatsink but in the UK it costs £25 and its too much for what it is. Can you recommend an aftermarket heatsink which isnt too tall or wide for less than £20.
