My PC's core temperature is getting above 80 degrees Celsius!

[InfinityBurns]

Hello. I have the Dragon Slayer II PC by Cybertron. Yesterday my computer started to run super slow, and it became laggy even when I tried to use Firefox. I thought it was a virus, or Malware. I did a scan with Malware Bytes and MSE but nothing came up. So I then installed CPUID HWMONITOR to track my computers temperatures. When idling my CPU gets around 30-40 degrees Celsius, but when I am on Mozilla it gets up to 60-70 degrees Cel. When I boot my computer up, my PC's Cores (Core #0, Core #1, Core #2, and Core #3) start at 50-60 degrees C, which is pretty high. When I try to play a non resource intensive game, like Minecraft, the temperature of the cores still shoot up to 80-90 Degrees C. When I try to play a normal game, like Watch Dogs, it shoots up to 90+ degrees C. Twice it has force shut down because the Cores temperature has exceeded 100 degrees. I took the side of the computer off, dusted EVERYTHING off with a pressurized air can, and made sure the fans worked properly, which they did. I currently have the Corsair H60 liquid coolant, and I think that might be why it is heating up. I was told that you were supposed to replace your liquid coolant every 6 months, and I got mine in early December. I looked on the processor, and it looked like it needed more thermal paste between the Corsair and it. I don't currently have thermal paste right now, but I bought the Corsair H80i liquid coolant and it comes with a thermal paste. I am hoping that that will fix my issue, because my computer is such a pain to do anything on now because of this. Help please!

If you still have a warranty, just call them before you try anything other than dusting your system.

CPUs get hot on start up because the fans are slow to come up to speed.

Idle temp of 40C is too high unless its a really hot day.

Game temp of 90C is ridiculous.

Shut the pc down and phone the shop. They'll want you to bring it in.

Yeah I don't understand why it just all of a sudden started doing this? I haven't messed with the internals of the computer until today. Before I put my new corsair back in, I will call them. If they don't give me the answer I am looking for, I will take it to the shop, thanks for your replies

I've also sent in a support ticket, but I doubt that will get a response. The warranty is 2 years, so it still is good. In the morning I will call.

Yeah just don't mess with anything if it is still under warranty, just have them help you with it or else you can void your warranty.
