Alienware 18 CPU temperature issue

I have had Alienware 18 for about 3 years. I have upgraded GPUs to 980m sli and A12 BIOS. After changing to 980ms, I have noticed that temperature of CPU easily goes up to 70-90 degrees under heavy load. The temperature fluctuate a lot when using. Randomly, it goes beyond 90, like 92, 93. I have changed the thermopaste. What else could be wrong? Is it an issue with the fan? Or should I check thermal paste again (cuz it might fail again)?

Thank you

 

What were your temps before? 70-90c is pretty standard fare for Haswell CPU's.

 

I think I usually saw 70-80s before.

 

You could try get a laptop cooler, or ramping up the fans with a Program called HWINFO64 (make sure EC Support is Disabled inside the program), and then of course the obvious thermal repaste. Personal Favorite paste I like to use is Thermal Grizzly Conductonaut. Drops temps like 20C on GPUs and CPU from the crap stock Dell Paste. Some Great stuff!

 

Thank you guys for the help. After repasting thermal paste, it is working usually below 80c under the heavy load. There was a spot that thermal paste did not fully covered. I think that cause the temperature issue.

Thank you guys again for the suggestion and help.

 

80C is still hot, do you run the fans at Max? I get 60C-65C Under load with a 4930MX at 4.3GHz

 

It does run at max. Actually, lower than 80c is what I expected.
I think our differences it is because of thermal compound. I repast with previously bought Arctic MX-4. You know, liquid metal thermal compound has higher thermal conductivity than traditional one. So, I wouldn't be surprised if 4930mx + Thermal Grizzly Conductonaut gives 60-65c.

 

Ah I used MX-4 years ago then switched to AC5 for a bit now on liquid metal... different systems different pastes I think I'll be buying liquid metal from now on though I really do like the results

 

Thermal Conductivity of MX-4 is like 8.5W/mK, where Grizzly Conductonaut is like 73W/mK. I can see where the extra 10c goes! I am just afraid that I might messed up with liquid metal, so I keep using MX-4.

 

I've used on my laptop personally and a few friends laptops... I did drop some on the motherboard but still booted and is working to this day... So idk I dropped a tab on the pcb on my 4940mx but I was able to get most of it off. Again works fine. So I think fear is what u make it. Don't be afraid to do things in life, that includes using more conductive thermal paste lol

lol true. So, what changes did you do on your AW18, except 980m upgrades?

 

Came stock when I bought it just Memory and CPU so far

Where did you get CPU from? And, what memory did you switch to?

 

The Corsair vengeance set its in my signature... And got the cpu off ebay lots of MXM Cards and laptop cpus up there
