I realised the reason my HP ENVY 15 is shutting down randomly and the way to correct it from shutting down is to buy a Cooling fan which wont let it overheat. What sizes and cooling fans would you recommend for me ? 🙂
Buy for quality and not price. Expect to spend somewhere between $20 and $60 US.
If the vents are on the bottom of the notebook, it is imperative that you allow space under the base to allow air circulation. Elevate the notebook base away from solid surfaces.
Select a cooler that provides more than one fan, if possible.
Ensure the cooler pad is sturdy - whimpy pad provides whimpy support.
Read what others say about the product -- consider good and bad reviews.
An on/off switch on the cooler is real nice; you do need to remember to manually shut off the fan.
Some products provide an adjustable fan setting - nice if the product also provides other features you like.
Consider: If you are using the notebook in one location AND that you are pushing the notebook's electrical capacity for USB devices, connect the cooler to a USB Hub that provides it's own power supply (and on/off switch).
There is "new tech" available that provides cooling using other than the traditional "cooler pad" arrangement.
