• Laptop overheating

Ok so I have this Samsung P580 Laptop, almost 2 years old, here are the specs: Intel Core i5 CPU M480, 2.67 Ghz 4.0 GB RAM Nvidia Geforce GT 330M Windows 7 64 -bit Ok it's quite shit for todays standards, but I just play games like killing floor, CS:GO and games like that which don't require a very good PC. And I'm happy with this because I've had much worse computers in the past. Up till a few months ago the computer was fine. I played games for hours without any problems. Lately though it started and freezing, for example the most common problem is after about 10 minutes of gameplay (all games exept very light ones like Binding of Isaac) the CPU goes up to 95° and the game's fps goes down to 1 for a few seconds, then goes back to normal. And this keeps happening every minute or so. I looked online and from what I read it's the CPU that takes a small break in order to get cooler. I fiddled around with Nvidia control panel, then instead of freezing the computer shut down. I put back settings to normal and that stopped happening. I tried a laptop cooler but it still happens (not as often, but it happens). I've tried opening it and cleaning dust but there doesn't seem to be any. Maybe there are other solutions? Maybe I have some processes that are slowing down the pc, but I don't know which ones to keep and which to eliminate I also use Ccleaner and Malwarebytes regularly to keep it clean. I dunno, any help?
You might have to dust out the computer. Also, try monitoring with HWmonitor if you haven't already. (Some programs can measure it in a bad way, causing misreadings sometimes)
Does warm air come out, about 30/45 degrees Celsius? If it is you might have bad cooling paste, (the stuff that disassipates heat between the chip and heatsink). I had a similair issue with a Fujitsu Siemens Amilo XA2528. And indeed give the machine a good cleaning, the only fan in the laptop blows air against a heatsink, which might also take a lot of debris and eventually cause a bad airflow
I opened it and wiped some dust off the fan. Doesn't seem to give any stuttering problems anymore, but it still switches off with some games. I'll try giving it a proper clean.
try re-applying with some good thermal paste
[QUOTE=Killervalon;40222970]try re-applying with some good thermal paste[/QUOTE] Ive fixed about 6 overheating laptops this way. The thermal paste used is usually absymal. And the small heatsinks get clogged up with dust really fast. (inside the fan/heatsink housing)

Upping this ancient thread cause I'm still dealing with the problem. I've given the computer a thorough dusting, and replaced the thermal paste with the help of an IT guy so I'm sure the job was done correctly. still overheats. got to 103c today while watching a movie on it. starting to think it's permanently damaged or something. Any other suggestions?
Warm air coming out the side is a sign that it's working fine. If the fans are going full tilt and it's cold or just about blowing really hot air out then you have a problem.

Any other suggestions?[/QUOTE] Usually if that happens because: A. There's a "carpet" of dustfuzz on either side / inside the heatsink fins that needs to be peeled off and cleaned with compressed air because it's blocking airflow B. The heatsink isn't making proper contact with the CPU / GPU (if it originally had a thermal pad instead of paste, you may need to make copper shims to use thermal paste) C. The fan isn't spinning up correctly If you keep the bottom of the computer open and then run something intensive, then touch the copper heat pipe between the cpu and the heatsink, it should be really really hot. If it's not, it's not getting contact with the CPU. If the fan's not spooling up (by pushing hot air out the heatsink), then you can check that in the same way too.
fan seems fine, but I can't check it since speedfan and hwmonitor don't even detect it. And there's no info in the bios. So no way of finding out if its spinning regularly or not. Seems fine from the outside, a little warm air is coming out, no cold air or blasts of hell. I'll have to open it and check the heatsinks and the fins you're talking about. Although I already opened it twice and blew every single bit of dust out.
Cooling mats can help with the intake on the bottom of the laptop as it tends to have a very low clearance from the table and airflow can be quite restrictive. The fan's bearings may have become clogged with dust over time which slows it down, so you may have to pull the fan blades off, clean that out and re-grease it. As for the thermal paste changing, the inside of a laptop can be a brutal environment for most TIMs, with something like Arctic Silver being better suited because it's designed to solidify and have better thermal transfer or Coollaboratory liquid ultra because gallium does not dry out, so the transfer performance won't be negated over time.
I used to have a cooling pad, it made almost no difference at all (was cooler by 1 or 2 degrees). I'll give another thorough check to the insides. Also I've noticed my CPU usage is spiking a lot whenever I'm doing anything. Opening chromes shoots it up to almost 100% usage, navigating makes the graph spikey as hell. And this goes for most things I do on the computer. Maybe there's a problem with the cpu itself? Could be due to the heating as far as I know.

Its trying to get what you requested done as quickly as possible and opening something like a web browser is actually pretty resource intensive.
If speedfan or HWMonitor doesn't work, try True Temp. It's designed for (all?) Intel processors. Also GPU-Z named program should work for GPU's more reliably than SpeedFan and HWMonitor sometimes. Then again it is clearly evident your CPU is overheating, and those 90-103celcius figures easily explain games freezing to a halt for a second (to cool down) As for web browser, they [I]can[/I] ramp up temperatures like as if playing a video game. Oddly enough.. When I dusted my semi-old PC, idle and web browsing temperatures fell by 20 degrees no kidding. As for your laptop, I'm thinking the temperatures have always been relatively high when playing, like around 70 to 80, which is actually fine most hardware are built to last. But when it starts rising from there and showing problems, it's probably dust somewhere hard to reach (heatsink area), and/or thermal paste getting dry from all the gaming over the years. And laptops are certainly harder to take apart and clean than desktop PCs. And laptops probably suffer from overheating issues generally more often as well. So if nothing else, I hope that your laptop at least had a good run..
