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)

 

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

 

It'll probably work. Never sacrificed a SATA slot before, but have used backlight connectors, usb ports and soldering directly to the battery connector. All of them powered fine without the component being present (apart from the battery, of course). But if it refuses to power on, then buy a defective drive and strip it of everything except the pcb and solder the fan's wires to that. Benefit is that the fan is easily disconnectable.

In either scenario, just to be clear; you do not solder to the connector itself. Solder to the solder pads where the connector is attached to the motherboard (or other pcb). If it's unclear which pad goes to which pin, then use a multimeter and measure resistance between pin and pad. Also solder the wire to both voltage and both ground pins, so it'll connect to all four pins.

Be aware that the fan will run 100% full time, unless you splice in a voltage-regulated fan controller. This type does not use pwm and can be used with 2-wire fans, like your 80mm model. The thermal sensor should be glued to the cpu heatsink, preferably using a two-component thermal adhesive.

Lastly, this odd-bay fan can solve an overly hot base (and thus ssd, kb and palm rest), but it will do little for the cpu and gpu. If these are overheating then a repaste with a liquid metal type of paste will fare decisively better. Also make sure there's enough breathing room for the air to pass through, same thing with the odd fan. This usually means drilling holes and other, assorted case mods.

 

I am a bit afraid of liquid metal (could shorten the stuff), so using the alternative high end thermal greases, although they are expensive and still less effective than liquid metal... Thank you very much for such advanced technical reply, t456 ! Now I understand more clearly how it could be done, will be trying out this mod soon Kudos to you

 

I'm curious why you haven't opted for a slot type fan. Seems like it might pull/push more air the way you intend. Something like this: https://www.amazon.com/gp/aw/d/B01B...m+slot+fan&dpPl=1&dpID=412CzkvS3AL&ref=plSrch

 

You mean like the Acer Predator "Frostcore"?

 

This slot-mounting system is aimed on desktops, not laptops, also can't trim a metal part to 9.5mm - will need to remove. Also I can't find any indication on this page that this fan is 10mm, and the price is too expensive, $10 for 1 fan when could buy 2 fans for $7 directly from China... Thanks anyway for trying to help

Mine is just a cheap low-end Lenovo laptop. Although it is not that hot (max temperature is lower than CPU throttling temp) I heard that lowering the temperatures could increase a laptop's lifetime - so I am trying to lower it as much as I could Already drilled some holes in case, applied good thermal grease, installed this ( http://www.aliexpress.com/item/Mini...CPU-Cooler-for-Notebook-NI5L/32612770600.html) from one side of laptop, and going to put inside the extra fan which will be working from another side

 

Hi again guys! Despite slimline sata port has only 5V voltage pins, there is no need to limit yourself by searching only 5V fans. There is $1 small magical circuit ( http://www.aliexpress.com/item/8W-U...le-Power-Supply-Boost-Module/32597140534.html) that converts from 5V to 12V so maybe I could get a higher speed fan with the same dimensions that is 12V (don't care about power consumption as long as it is lower than what slimline sata port could provide - 1.5A at 5V, means 7.5W max)
