Laptop Constantly at 100C

sardinesrule · Jan 27, 2014

My laptop is consistently at high temperatures (60-70 when idle, 100 when gaming). I've tried to limit the maximum processor state to low numbers, however, the temperatures are still extremely high. These high temperatures are causing my computer to throttle intensely, which leads to extreme FPS drops when playing games

. Is there any way I could stabilize the FPS? I've tried using Throttlestop to decrease the maximum speed by extreme numbers, like 50%, but the throttling is still happening.
Specs:
Lenovo E420
i5-2410m
Intel HD 3000

Physical issue, the fan is probably dead internally or dust is blocking air from getting in or out.

that processor is very low power and you have no dedicated graphics so i would expect load temps to be in the 60s-70s range. 100 is WAY TO HOT. chances are your fan has failed. i would send that laptop to lennovo to get it fixed. i dont know where you live but i would get a hold of lennovo or if you bought an extended warranty at a place like Best Buy or something like that and talk to them.

The thing is, air is blowing out of my fan.
Also, I took out the keyboard and looked at the fan, and it seemed to be spinning along just fine.

Is this 100 Celsius or Fahrenheit?

That chip will melt at 90c, I can't imagine it getting that hot

Where are you getting these temperatures from?

Alec Mowat :

100 Celcius. Getting it from HWMonitor and throttlestop (I used both to be sure)

Did you play with the power profile?

it's almost like the heatsink fell off the CPU or something. Did you drop the laptop?

if the fan is blowing COLD then something is wrong with the heatsink itself. i think you need to re-paste it. either that or one of the solder joints on the heat-pipe assembly has broken if the heat-pipe assembly is broken then i would RMA. if its still in good shape i would re-paste it. so to re paste go to the computer store and get some good thermal paste (IC diamond, MX4 and prolimatech PK1 and noctua ht1 are good choices) you will need to tear the laptop down to get at the fan though unless your laptop comes with an MSI style cover. remove the heatsink and clean the old thermal grease off using Arcticlean or rubbing alcohol. then apply a very small amount to the processor and spread it on the die then reseat the heatsink and reassemble. i have done it on several machines and it works well.

Yes, I did drop the laptop. That's probably the issue. It's falling apart anyway, time for a new one
