Laptop is getting hot

pennypincher2013

All this week, my laptop has been getting hot. I downloaded speedfan to check the temp which is ok at the time of typing but could go higher at anytime. At it's highest, it is 54C.
I don't know if this has anything to do with it but in task manager, the disk is reading 95-99% a lot of the time, CPU is variesfrom 40-55% but this afternoon went up to 99%. Kaspersky is the only thing that appears to be taking a lot but I'm not willing to stop my anti virus.

Tomorrow I'll buy compressed air to see if that will clear out any dust. But I have a feeling that's not the cause.

Any ideas?


p.s. by time I finished typing temp is now HD0 40C, Temp 1 52C, GPU 50C, core 54C and CPU fan 3093RPM with CPU 70% , memory 43% and disk 99%.

CPU temperatures reported by Speedfan aren't reliable on laptops unfortunately as they are all bespoke designs with different throttling methods and ways of working.

If this is a budget brand of laptop like an Acer, Gateway or Packard Bell or something, nine times out of ten the problem is caused by a build up of dust on the outlet vent. This will not be cleared by a can of compressed air, the laptop will need to come apart to get rid of the major dust bunny that causes the heat issue.

Do you use it always on your lap, on a soft surface, perhaps on a cloth or cushion? That's what my neighbour did; used it on top of two folded tablecloths. I stripped it, cleaned out the dust (it was agricultural) had to reinstall drivers, as it just gave up. That was challenging, as it was a 5 year old Samsung and Samsung are rubbish at retaining drivers for Support.


Then I advised her to use it always on a hard surface, preferably buy a laptop stand so that air could pass underneath and aid cooling. They should never have been called laptops, never be used exclusively for long periods on laps, without a hard surface underneath or even better, a raised stand.

I had the same trouble, and when it went to the repair shop it was something to do with the heat sink - it's as good as new now, but it does need taking apart and not sure what they did - either renewed it or cleaned it.

I seem to remember now that maybe the fan casing has some sort of substance on it that had disintegrated and needed replacing - might have been a tube of something "thermal".

My MacAir only gets warm if I am doing a jigsaw on it for some reason, and the fan is a bit noisy. Never figured out why I just do something else for 10 minutes until it cools down

They'll have removed the heatsink from the CPU (and also possibly the GPU), cleaned both sides up (chip top and underside of heatsink) then refitted them with new thermal compound (which improves the transfer of heat from the chips to the heatsinks).

It does sound like some software is making the computer work hard. I had a Chrome extension that did this on mine once, which took a while to identify as the problem. Also malware can have this effect so have you run a scan of something like Malwarebytes? I don't know how well Kasperski detects malware.

Step 1 is visually inspect fan in and out grills and if dusty use low power hoover to suck out dust (with laptop off); take care doing this; you may want to prevent the fan from spinning while doing this by inserting a small screwdriver to prevent fan from turning (obviously take care here too!).
Next, find out why CPU and disk access are high. This may be just anti-virus but could be Windows Update.
Temps. HD temps look high; should be nearer 30degC (try HD Sentinel); CPU temps. The values you've printed are NOT high. Mine is reporting 50-80 degC. and mine **needs CPU/heatsink thermal paste renewing**. Try Notebook Fancontrol for alternative way of reporting CPU temp (NB. this is a fidly program but may give a better CPU temp) OR BIOS may report CPU temperature. It IS safe upto 80degC but if you have noticed a recent change in fan noise then there is probably a problem to sort out. Report back.

If you're running Windows 10 then there are lots of problems causing disk usage at 99%/100%. I've just spent a couple of days sorting out 2 desktops and a laptop at work with this issue - one desktop was an issue with iCloud, the second desktop was an issue with RAM settings and the laptop was an issue with anti-virus.

Google it, there are lots of online guides of how to identify the issue with a number of steps to check until you find the problem. All 3 of my machines are very similar with the same software installed, and the 2 desktops are identical, but it was a different issue on each.

CPU temp at 54C is nothing to worry about, they don't even begin to think about throttling back the speed due to overheating until well over 80C.

Get a can of compressed air and blast the side vent in short bursts (whilst turned off).


Your disk usage is almost certainly unrelated. Recent upgrade to W10?
