CPU Overheating, Thermal paste make a lot of difference?

My new computer's processor is overheating pretty badly. It makes my games crash, become unresponsive and sometimes even shut down/restart the computer. I checked the temperature after attempting to play a game and both cores were almost 70c.. deffinately wrong. I turned the computer off and won't start it again until i re-apply some thermal paste (the company clearly didn't apply it right).

My question is; Will re-applying some thermal paste and making sure the heatsink is seated correctly help the the temperatures a lot? Oh and also.. Do heatsinks get hot? Because when i turn the computer off after crashing and touch the heatsink it is room temperature. Maybe it isnt working properly or at all?
 
Thermal paste is very important it completes the contact surfaces of the cpu and heatsink. Without properly applied TIC it is very likely that your cpu will overheat. If this a Dell or whatever I would call them otherwise you can buy some aftermarket paste (most will recommend Arctic Silver 5) and do it yourself.
 
And it is very important to clean the old paste off correctly. Use some denatured alcohol to clean it. Do not use rubbing alcohol, it is not very pure and will leave it's own residue. You want to make sure there is no residue left of the old paste. Place just a small amount on the cpu and install the fan.

70c is way to hot for a cpu, I am surprised you did not fry it.

Heatsinks are designed to stay cool, it should be warmer than the surrounding air though. Especially if your cpu is that hot. You might try an after market cooler if you are using the stock cooler. Make sure you do not have a bunch of cables blocking the air flow inside the case.
 
I'd rather spend a little than wait a month for my PC to be returned, because let's face it.. A free repair isn't going to be high on their list.

So yeah, i'd much rather do it myself and get it done quicker and properly.

Good idea.
 
I'll try with the stock heatsink first, if the problem persists after i've tried re-applying the paste i will look into buying a new one or getting the company to send me one out.

Also; what is a good, steady temperature for an Idle core 2 duo E4400 ?

It was idling at 50-54, shooting way up to 65-70 on load.

32 to 38 would be a good temp at idle

My E4300 was at 32C idle. So an 30-35C should be an fair temperature.
 
Yeah, thermal paste and new Heatsink... For some reason Dell always comes up short in their line of duty.. The customer gets shafted for it :rolleyes: DELL!?
 
I removed the heatsink and.. NO thermal paste whatsoever had been applied.. Also the top right of the CPU had been scratched where they had not properly seated the heatsink. One of the screws in the heatsink doesn't have the same length of thread as the others. Absolute shambles.

I bought a new Intel heatsink and fan with pre-applied thermal pads but it didn't fit properly in the holes as it was a clip one and the original was a screw-in one.. Going to go to the only place open on Sundays tomorrow, PC World... and hope they have the right one in stock.
