He is very happy with it.
Why is that you need a cooler may I ask ?
Does the lappy run hot ?
Answer #2
I’ve only got one lappy that runs hot, out of 6, and that’s an old Inspiron 8600. A laptop cooler from my local 99p shop did the trick.
I can’t see the point in you investing in one now, if the lappy isn’t going to run hot ?
