Hi,
I am using my old gaming laptop for college now as a portable computer and in the last half year I have noticed a huge drop in performance and an increased frequency of my fan being on full speed even during idle. I suspect that either the heatsinks are clogged with dust, or the thermal paste has been withered down in the past 2-3 years. Any other input on this? Thanks.

Here are my HW monitor results(idle):

Well your GPU is hot and apparently not even under load... you might want to have a look under the hood. Maybe turn off Aero if you are using Windows 7. Your CPU is warm but the temp that caught my eye was the GPU 460m @ 70+C while idle.

what i can think its that the gpu propably need a new thermal paste. Your cpu is getting hotter because i assume that ur laptop has only one exsaust and it cant cool both cpu and gpu down so the cpu is running hotter than normal. If its not a thermal paste and its not a software issue then the gpu may got cooked up

Thanks guys, but is it worth paying 100+ to reapply the paste and get it dusted, or should I just save up for a new laptop?

It is a gaming laptop, so it has two exhaust ports, one for each. So I think that it is probably the Thermal Paste.

If you are sure that the dust its not the issue(you can try suck the dust with hoover) then you can also try download/updating drivers for your Gpu and also download the intel hd 3000 driver and use the integrated graphics of the cpu. You can set your gpu to not be used for light processing or when its idle. So you will be able to use your cpu but when you enter a game the gpu will still run hot. Arctic 5 silver is about 10 euros so if you can apply it by yourself it almost cost you almost nothing. There are many videos in youtube on how to disabling your laptop. If i was you i wouldnt buy new one but try to fix it cause the components are good.

Changing the thermal paste should be the last resort. Since yesterday, I've been trying to find the culprit of my CPU's high idle temps (70 degress celsius) and unusual activity using the task manager. (Take note that the room temperature is around 25 degrees celsius.) That's why I didn't find the culprit right away until I used 'process explorer' to give me a detailed info on the processes that are running on my system. As it turned out, it was the 'IAStorDataMgrSvc.exe' from Intel Rapid Storage technology that's causing the CPU to work and idle at 68 Degrees Celsius. I killed the processs and voila! The CPU temps are now averaging at 55deg Celsius!

Open your task manager and look at your CPU activity graphs. Close other programs that are CPU intensive. If it still shows a significant CPU activity then you got a process that is hogging your cpu causing it to idle at those temps.

Again, I should tell you that changing thermal paste should only be the last resort.

If your GPU is hovering in the 70C range at idle..... either the heat-sink contact is separated or you have a fan that is not spinning or the air-duct is clogged or combination of the above.
