I'll show the Simplest way to Cool down your laptop's palm rest on the cheap.
Next page please...
Step 1: Whats Hiding beneath?
Hard drive heats up the palmrest, Making it uncomfortable to type on.
My beast had not One, but two Of 7200 RPM HDDs in RAID 0.
Blazing fast and just as hot. Its common to reach temps of 45~46 on Idle.
Step 2: What to Do?
Remember the FreshWrap Foils to keep food fresh?
Those simple Foils are designed to insulate the heat...
Which will prevent the heat from HDD to travel upwards towards the palmrest and Spoil the fun.
Step 3: Preparation.
I can't stress enough the importance of this step....
You risk loosing the HDD, The DATA or even the whole Laptop if you skip this one.
I simply coated the Underside of HDD (Circuit) with a plastic sheet to prevent electrical Short-Circuit.
