Laptops Home Made Laptop Cooling Pad

[Haddock]

I saw some laptop coolers in market, like the coolermaster.
They had the cooling slots at wrong place, most of the coolers either missed the Ram or HDD spots.

So, frustrated as I was, I thought of ‘why not build my own cooling solution?

So after spending a mere 50bucks for the thermocol, I laid out the laptop under body (air vent) location. (See pic 3rd, 4th)

The fan is a spare cabinet fan, I used my old broken gamepad’s USB cable and joined it with the fan.

When keeping the fan near the processor & graphics car outlet, the temp. of Gfx Card is at 50degree Celsius.

Idle Temperatures
Before:
Gfx card - 53-55degs.
HDD temp - 55 degrees
After:
Gfx card – 50degs
HDD – 48 degs.

No major changes in CPU temp, still at 57 & 59degs (core 1 & core 2 resp.)

I Dunno how to take RAM temperature






I want your expertise in placing the fan.

I want the optimum place (at rear ), from where all the three slots get cold air & obviously a output.

This is basic layout, I wanted to test this design.

Didn’t cut much of the thermocol because, then the weight of laptop will upset the ‘level’ (overall height level).

Once I get a good design, then I’ll send this to some plastic molding company (small firms who do projects for college noobs).



So far, I’m happy with the time spent on this, over the weekend. hyeah:

btw, is there any software which benchmarks the load & temps of 'proc., gfx card, HDD, & RAM'?

nice job..

time well spent..

Good, nice work

^ way to go,bro!

very nice, perhaps, write up a good indigenous tute on this?

 

[thetoxicmind]

Good work mate.

You could probably experiment with better fans, next time?

And maybe, add some OOOMPH to the thermcol, for visual appeal.

thanks guys

this fan is running w/o noise, a really big advantage.
but i'll be using two or three small 30mm fans, saw them in a shop, which you see on HDD coolers.

i need electronics/electrical experts' help here
those small fans are rated at 12v, i want to power them thru USB.
& my laptop has ONLY TWO USB ports, so i'm limited to use only one USB port.

Will there be any problem if i run the 3 - 12v fan with jus 5v?
@thetoxicmind, the thermocol is temporary, once i get the temp. under control, I'll send this for molding
btw, when under load (gaming), the temp hit a max of 75degs, its still hot, but a bit better, 3-5degs. lesser than before

so this layout need a lot of tweaking.

this seems to allow placement of fans in diff position hyeah:

I dont think your kinda custom design is good for laptop cooling dude. bcos the thermocol is obstructing the free flow of air under the laptop. the heat is made to spread to the entire base of the laptop so cooling just the cpu or ram/hdd place is not enough. anyway nice experiment :cool2:

IMO its better to leave some good amount of space under the laptop (say 3 ~ 4 inches)

just use a elcheapo laptop stand like this and place a small fan in the rear thats all is needed (like those small usb fans with flexible neck.. but they make hissing noise which will be irritating).

Cool, save the OOOPH for that.

Very Nicely Done..

Waiting to see how it turns up after you get it molded..

Get a USB hub, you will get 3 more ports.

like i said, the cooling pad didnt suit my needs.

either they block some ports or they are too small for the 17"

length of the laptop is 15.5".

btw, that coolermaster notepal has given me a idea

USB hub would divide the 5v from the laptop to 2 or 3 fans, right?

i'll sit & re-design the seatings on this weekend.

 

[Haddock]

updated the design a little bit.

added a new layer (at laptop seat positions) with 1cm thick thermocol.

increased air flow area. with this new layer, the laptop's bottom surface gets a lot more air (non force cooled areas).

massive difference in CPU temps. :clap:

finally got the CPU temp. under control. :cool2:
