Yes. A major part! The heatsink and the fan keep your processor cool. Without them, the laptop will overheat and shutdown completely.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

My hp pavilion model g6-2240as when restarting, states that the fan is not working properly and then cuts out in about 15 seconds. I do not know what to do. It has windows 8.1 operating system and the...


This is a common issue with laptops. Quite often, however, the problem is not the fan, but the heatsink that the fan blows the air over to remove heat from the processor. People tend to lay their laptops on their laps, beds, sofas, and carpets when they use them. This sucks massive amounts of dust, hair, lint, etc. into the cooling passages and clogs the heatsink. Many laptops are now made so that the heatsink can be removed for cleaning. If the heatsink is clogged, the fan cannot cool the processor and the processor overheats. This causes the cutting out for processor protection.

HP 6200 pro microtower the PC power led turns on but there is no display and after a minute or so all the fans starts running very loudly


Sounds llike the system may have overheated/is overheating. Open the case and look for the fan and heatsink. Check that the heatsink fins and fan are clear of dust. Also, make sure any vents are clear as well. You could also remove the heatsink from the processor, clean both where thay meet and apply some thermal compound before putting back together.

I buy an HP pro book 4520s but its have huge noise from the Fan and getting too much heat and then when i play a game on it turn off


you can try getting a can of compressed air and blowing out the vents. if this doesn't work you will need to open the case and clean the vents from inside. clean the fan and ideally remove the heatsink and apply thermal paste to the processor where the heatsink sits.

Dell inspiron e1505 power cuts out. Battery health is good and charged.


hello

one reason i can think of

issue could be the heatsink fan : it will need to be replaced, along with thermal compund applied on heatsink and CPU. This is a strong indicator , as the system defaults to fusing the issue by cutting out power from entire system to avoid further damage to CPU and/or mainboard.

if youc an give me the service tag # i can look up the ehatsink issue and or further investigate to enusre it is a heatsink fan issue

one way to determione this is to see if fan is running after power up. Locate the fan by placing hand away (1-2 inches) from grill where air is supposed to blow out. If no air blowing out, then this is the cause.

please let me know

The system on booting says "There is some problem with the cooling system. Either fix this problem or give it to the service center."


Try cleaning the air ways and fan. If that doesn't help, remove the heatsink and fan, clean the processor and use fresh heatsink compound.

Overheating hp compaq 6735s


The overheating problem can be caused by a faulty fan and or dust clogging the fan and heatsink assembly. If the fan deos not spin freely then it is faulty, also loosen the dust and vacuum the dust from the fan and heatsink.

Shut down during use


If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. It’s nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.

  1. Open the laptop case, so you can access the CPU fan and the heatsink. In some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes you have to open the laptop case all the way down.
  2. Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
  3. Clean the fan and the heatsink with compressed air.
  4. I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.
