Intel i7 4800MQ Temps Dangerously High

I've been told quite a few times that the 4800MQ is the hottest running CPU in Intel's current 4th gen line up, but I had to see for myself just how hot it really runs. I played a various amount of titles for about 3 hours. The longest being WoW for about an hour. I was also streaming with Open Broadcaster Software to Twitch, with a custom quality setting enabled for a better stream quality. After 3 hours, this is what my max temps looked like.



That's really damn high, especially since my SLI 780Ms never reach above 88C under a full load. I've already checked the thermal paste does anyone have any suggestions on how to get those temps lowered?

 

What laptop do you have? Did you make sure it gets enough of airflow?

Ill assume the 9380/9390 which has a smaller cpu fan. That could be normal temps depending on the load you throw at it.

 

Correct, I have the NP9380-S. Do I risk damaging the chip in the long run at those temps? Is it worth investing in a cooling pad?

 

You can try raising the back a little and if they stay high then maybe a repaste but its not going to damage anything as it is.

 

CPU's are generally very good at being able to handle heat so long as you keep them under the limits. These limits exist to avoid permanent damage to them.

That said things will generally always last longer if kept cooler but that is not to say it wont last well beyond what you keep it for.

If you kept it at these temps 24/7 365 I would worry a lot more but if it's just for random 2-4 hour game sessions you will probably be fine though is close to the limit so not uncommon to worry.

That said at those temps a cooling pad would probably help you and running at these temps you will need to make sure to stay in the habit of ensuring the FAN and cooling components stay clean of dust.
Room temperature will also play a role in the heat so the cooler the room the better.

Keep the back from being up against a wall or anything and raising the notebook some will always help a little.

 

To be honest the cooling pads get most of their performance from the back being raised up, they have little to no effect on the clevo machines.

 

My 4800QM gets up to 78C under benchmarking in XTU.

Haven't done a stress test yet.

 

Try undervolting the CPU, you'll usually drop temp by about 5C.

 

Well remember the xtu stress test is an extreme case.

 

Yeah, thats why I wont be doing it.

 

Btw got my 4800QM running at 4Ghz with no throttling xD

Under what situations?

 

how do you oc?

 

That is physically impossible as the 4800MQ only goes up to 3.9GHz mac OC for 4 cores. 4GHz only happens if only 2 cores are running.

 

As a fellow streamer, OP, I say your temps looked like what mine were doing to be honest. That being said, I have one of the hottest rooms ever, so glad to know 95deg max on a core or two won't kill it... but I hate running 90+ degrees for a long period of time as a matter of principle.

As for ways to cool it, try running it with a -80mV dynamic core voltage offset setting. If you do NOT have an unlocked BIOS (which comes standard with Mythlogic machines) then you'll likely need to use Intel XTU or get an unlocked BIOS for your machine. This SHOULD run perfectly fine, even for streaming. IF, however, your machine does crash for some reason, I suggest changing the -80mV adjustment to -50mV. It should be more stable. Otherwise, just try a cooler room and see if you get a way to raise the back a little. I was kind of disappointed at how un-raised this machine was, compared to my old D900F, but oh well. Everything can't be perfect. ALSO MAKE SURE YOU'RE RUNNING ON MAX FANS.

If repasting is your game, good luck. Pick your paste carefully; I originally repasted my machine because I thought I had a really bad paste job... nope. The new paste ran cooler for about a week then temps went back up. We tried to repaste it again and found the thermal paste had EVAPORATED. There was literally almost nothing left on the CPU or the heatsink. So don't use any low-grade paste.

 

Strictly speaking if he managed to get his BCLK up to 102.57 MHz then he could rock 4GHz on 4800MQ.

And yeah MX-4 is a good all-purpose paste, though performance does seem to degrade after only about a month.

 

just simply buy a new copper cooling module. i just bought a new one for my 3940xm on my p170em. the solder of the old one is very bad. if the wind blowing out is not hot enough, 99% is solder problem.

 

Heatpipes can also vary in performance.
