Laptop overheating

post #1 of 12
Thread Starter 
Hey everyone. I've had my HP G72 for awhile now, and since I've had it I noticed it has some overheating problems and sometimes runs a little loud. Now the laptop came with a 5400rpm hard-drive, but I quickly swapped it out for a faster 7200rpm one. Would something like this cause an overheating problem? Maybe the laptop came with a 5400rpm drive for that reason? I don't have the original drive anymore, so I want to rule out other possibilities before I go buy another.

Its strange. The fans run pretty loudly so I'm not sure why its still overheating. I haven't had it shut down on me during actual use in awhile though, it mostly happens when I close it and leave it overnight (while still being on/sleeping/etc.). I wake up and see a thermal shutdown error which makes me reboot.

a 7200 rpm hdd will run hotter than a 5400 rpm, but i wouldn't think it would be causing your computer to shut down. I would open up your laptop and clean outall the dust if there is any. Also, download HWMonitor and report the temps of the different components, that'll help in figuring out what could be overheating if anything

It is best to swap out the thermalpaste on laptops, and every once in a while blow out all the heatsinks with compressed air of some kind (either from a can or air compressor).

What does it have for a GPU?

I have a G72-250us (core i3-350m) and it too overheated a lot. it idled around 65C, and playing any game would drive it to 90C where it would shut down. I have a friend with an acer laptop with the same processor, and comparing them at the same time, his idled around 40-42C, and never shut down no matter what he threw at it.

I did swap out the paste twice, at first I did it with some random gooey stuff that came with an old heatsink. it didn't make much of a difference. I went to Microcenter and picked up some of the better stuff they had (supposedly this thing was made of diamonds or something), that they recommended since they were out of arctic silver, and that seemed to drop it to about 47-50C, huge improvement over stock and/or old grease.

The main culprit with these laptops is the idiotic design. They put the CPU with the built in GPU, the harddrive, and the memory (which is 2 memory chips stacked on top of eachother) in one spot, out of the whole 17.3" real estate... and left other parts of the laptop completely empty - like the lower right hand corner, in front of the optical drive. Had they moved these components around a bit, it would have been much better IMO.

My plans for this thing are to add an SSD and a secondary hard drive caddy - found one that basically replaces the optical drive and provides room for a hard drive. Hopefully that will move some of the heat away, as SSDs are supposed to run cooler.

I did think about putting in a pci slot cooler in the empty space in front of the cdrom, but I'm not too great with modifications like that... if I can't find one that fits relatively well, I think worst case scenario, I did save some fans out of an older dell that should be thin enough to fit and at least point them at the memory (currently, I think this is the hottest point of the laptop, now that the cpu is running a little cooler).

I advise to get a laptop cooler/pad , change thermal paste , use compressed air to blow all dust out , check if the rear exhaust vents are open so hot air can get out. Also , I'm not sure if there is , I will try to find it myself , but I guess some software could help and set speed on laptop cooler. Not sure if possible thought.

I had overheating problems too at intense gaming , and got a cooler-pad. Now it has never shown me errors or blue screens. etc.

I will buy new laptop and will get a new , much better cooler pad too.

I advise this pad to you too. It's one of the best , maybe even The - best. I've read a lot of reviews , and all said that it was good , even some of my friend who have it said the same. Supports 17 inch max.



p.s. If you know some stuff about laptops , then please check my thread '' Laptop/s. One of 3 ? '' and what do you think smile.gif ? I really need some advise etc. but haven't got answer I wanted frown.gif

I should state that mine overheated even on a cooler pad during gaming; I have a coolermaster notepal - similar to the one linked above, it's basically a sheet of perforated aluminum bent so it has feet, with some rubber, and 2 fans that you can move around - main reason I got it.

I have not had it overheat since the second thermal paste change; but without the cooler the fan does go full blast, making it pretty darn loud.

The problem is finding a cooler that fits these behemoth laptops... mine dwarfs the cooler; I need one for a 19-21" laptop I think, if there is such a thing.

I have 17 inch laptop [ screen size ] , and will get a new one , after I get some good answers on my post.

But , my cooler that supports 17 inches , it's too small. Also , the cooling performance of it is like if I were blowing air through my mouth , it has 1 80mm fan. I also wonder if there are coolers for like 20-21 inch laptops. Those would be nice.

Will try to find one for like 19-22 inch laptops , if I get any results - finding something like that , will message you.

I have this for my FX and it works great!

That zalman with the giant fan looks good too! I like the CM one because I can put the fans where I need them. I have one over my HDDs, one over my 8800gtsm and one over my cpu. The HDDs needed it the most.

Aha! I have the 17" version of that, with 2 fans... I will probably get that one, the 19" version, and add my 2 fans to it... if 5 fans don't cool this thing down, I don't know what will. Next step up would probably be a home depot box fan... thinking.gif
