10mm 5V cooler instead of laptop's dvd??? (slimline sata)

Hi there. My laptop is super hot! (already replaced thermal grease, didn't help much 😛) so I am going to replace my laptop's internal DVD drive with a fan. Initially found two possible "solutions" :
1) http://www.aliexpress.com/item/Lapt...ventilation-radiator-turbo-2/32710721817.html
2) http://www.aliexpress.com/item/2016...-NGFF-SSD-HDD-Optical-Driver/32660872781.html
===> But they are not suitable:
1) my laptop's DVD is 9.5mm, can't fit 12.7mm replacement with two fans
2) this one fan is too small, weak most likely, also don't need SSD (not as reliable as HDD)

Because can't find a suitable solution, I will have to build it by myself. Found these 10mm thin desktop-like fans:
[*] 2pcs of 5V 0.3A 2200 rpm 80mm*80mm*10mm fans - http://www.aliexpress.com/item/Whol...V-2Pin-PC-Case-Fan-80-x-10-mm/2026890945.html

80mm*80mm fits OK, to fit a remaining dimension 10mm it is possible to use a sandpaper to reduce it to 9.5mm.

Laptop's slimline SATA connector has 5V and GND pins: http://en.wikipedia.org/wiki/Serial_ATA#Slimline_connector

I never tried soldering a fan to these pins, and can't find anyone who did it before. Please tell, will it work if I solder one fan's wire to 5V and another one to GND ? if not, why? (i am a bit uncertain about should I do anything with a Device presence pin)

My first question is have you checked to see if the DVD bay even really ventilates anywhere important? Depending on the layout/design of your laptop, I don't see a fan in the DVD drive bay doing much for you.

DVD is not that close to CPU/GPU in my case, but still a fan there could aid in removing the hot air from inside the laptop, and if this mod could decrease the temperature by 10 C that would be great

I strongly believe that this is worth trying, but would like to research if this possible at all. For example: I don't know what effect "device presence pin" could cause... E.g. if a laptop tries probing a device through this pin (e.g. reading a device id code) before giving a 5V power, it will be quite difficult to work around: to solder two wires - simple, to fake id code - difficult

That is pretty clever.
