Friend's PC (CPU) Overheating After Thermal Paste Replacement
So I was helping my friend a couple of days ago on "repairing" his PC. It's a 3 year old PC that he uses a couple of hours every day. He said that it won't boot anymore after cleaning it. So I sorted it out to only find out that the RAM is not seated properly. However I also convinced him to also change the thermal paste in his CPU as part of his cleaning. I hadn't thought of taking CPU temps before the paste replacement because temps weren't my concern (nor he is) at the time. However when I installed HWMonitor I was shocked when I noticed the idle temps. It's hovering around 50~65 °C. When we tried to play Arma 3 (Zeus, testing the effects of high AI units), the CPU temps got around 70~85 °C and sometimes spiking to 90. The ambient air temp was around 32~34 °C but still it shouldn't reach that high (well I think it shouldn't). I know there's something wrong with but it seems I can't find it. The ventilation is very good (cables aren't obstructing the fans), we even had the side panel removed to see if it can improve some things.
I decided to test things further by using Nvidia Flow (kinda like Flex but for smoke effects). I know that the software is not CPU bound but I needed something fast and easy to use at the time. I was actually shocked that the CPU is reaching around 70~80 °C with this software (what more if I used something that can properly stress the CPU). Compared to my CPU when I had the Flow running, it doesn't even reach past beyond 58 °C.
I don't know if this is his real everyday temperatures because he doesn't monitor it. So I don't really know if this problem existed a long time ago or just when we had the thermal paste reapplied.
tl;dr CPU is hitting high temperatures after thermal paste replacement. Even at idle, the CPU is getting around 50~65 °C.
His specs:
W10
i7-4790 (stock cooler)
Asus H97M-E
8 GB (2x4) 1600 MHz HyperX
Asus Strix GTX 750 Ti
FSP Raider 550W
My specs:
W7
Pentium G3258 @3.8 GHz/1.092V (stock cooler)
Gigabyte Z97-HD3
8 GB 1600 MHz Ripjaws
Palit SuperJetstream GTX 1060
Seasonic G550 550W

Also in that thermal paste pic, I decided to have it reapplied (2nd time) but it's still the same situation.
He's not able to spend much on a cooler. So I'm planning to get him the Deepcool GAMMAXX 200 CPU cooler to replace his stock one. I've seen reviews of this and according to them, it's pretty good.
