From my understanding, stripping off the plastic shell from the back of laptop, which would expose the heatsink and fan, and adding a couple of desktop fans pointing at the laptop heatsink definitely should improve thermal performance, to significantly reduce temps, correct?
Non tl:Dr version
Currently my cpu is pushing 75-80c under load (i3 2130m), and the laptop gets exceptionally hot when doing anything gpu intensive (7670m)- it just shuts off.
Ive just upgraded the laptop's ram and storage so I am not keen to give up on it just yet, as now it runs very well for a 2013 laptop, EXCEPT for overheating.
I am certain that it's an overheating issue since it's getting very warm under load and the fan spins up like crazy. It has been cleaned a few months ago so I know it's not just dust.
My idea is that getting a pc case and a couple of big fans to cool it off would be much more efficient (and safer) than trying to repaste / add some custom heatsink to improve thermals.
I understand that putting it into a desktop case would mean I'll have to keep the laptop mostly in its shell unless I'd be prepared to drill custom standoffs for its motherboard.
I'll need to get a custom psu (like a mains to molex brick adapter) to drive the desktop fans as no psu will power on with just the fans attached to it (?). If my research is correct, most psus require being plugged into a pc motherboard to work, unless you short the 24 pin connector (something that I am not prepared to do). Not to mention that a 10w load (2 fans) would be very inefficient for even a 400w psu.
My only concern is that I am overestimating the cooling abilities of such a setup and that it won't keep my overheating laptop cool enough to work under load. Is this a valid concern? Am I simply throwing money away (um, I mean, getting a pc case for my next build a little earlier).
