Looking at the baseplate, of the Thermalright 120 Ultra I realised, as well as there being no clearance between the backplate and the motherboard, when fitted, there's precious little, between the backplate and the motherboard 'tray' !
Things might get a little bit 'toasty' :sweat: behind there, especially if overclocking, and we're trying to keep things cool, :cool: right ?

First, I decided to remove the centre of the Heatsink backplate :

Next I removed some metal from 3 sides of it.
(The fourth (left hand) side is left intact, to help deflect the proportion of (front fan) air, which finds it's way behind the m/b, outwards).
It doesn't show up well on a close-up, so hope this sketch will do ! :
('Shaded' area, where metal removed).

and : (Please ignore metal removed from upper left arm, that is to 'clear' a cable tie !).

A 37mm hole (I think) was cut in the m/b 'tray' to allow the heat to escape. (passive cooling) :

(Photo showing [eventual] position of backplate) :

A corresponding hole was cut in the right hand side panel :

A piece of grille, cut from a scrap case :

'pop' riveted in place :

Once the motherboard and heatsink have been installed, the reverse side of the CPU socket area, can clearly be seen, now ventilated !


For those of you who are wondering, what those 4 small holes are for, and for those that feel they need a little 'active' cooling, take one old graphics card :

Remove one (rather dusty) fan :

Extend the wiring, and screw to back of m/b tray, (if you drill 2mm holes, they should 'self tap') :

Your newly installed fan, can now be connected.

Now, Overclock the nuts off it ! LOL

Nicely done!

How big is that fan, 20-30MM? Is it noisy? Those lil' fans can drive ya crazy sometimes because they run at such high RPM's.

Thanks Blooz1, Fan is a 40mm.
Tried it out, and you're right, there was a little noise.
I lifted up the centre 'sticker' and put literally a drop of vegatable oil on the bearing, you'd be 'amaized' at the difference (If you'll pardon the very 'corny' pun) ! tongue.gif
Cheers :beer
