quick question

post #1 of 9
Thread Starter 
if using water blocks for the motherboard NB/SB, do you use thermal paste or just the rubbery strips that come with the motherboard?

under one of these blocks is about 16 little chips, so put a tiny dot of TIM on each one or go with the rubber strip thing?

thanks

Thermal paste > Thermal Pads

In terms of heat conductivity. Use the paste if you can.

Some blocks require thermal pads due to the gap. It would be best to check the instructions. If the block(s) didn't come with pads, you probably don't need them. If they did come with pads, do a test fitting and see how far down the pad is compressed. If the pad is compressed sufficiently, then you should be ok to use a thicker thermal paste.

Definitely check the instructions and check with the mfg. on replacing pads with TIM.

Use a thick paste if you can get away with it, but if the surfaces of the chips don't all line up pretty well you are going to have to use pads.

thanks

I got a bunch of copper ramsinks for my GPU because i'm not using a full GPU block, they have sticky thermal pads on them, but would it be better to remove those and use some MX-4? will it be able to hold them on? when the card is installed, they'll be upside down.


also another question; how tight do fittings need to be on rads/blocks? I tightened them as much as I could with my fingers and then used some pliers to turn them a bit more until the pliers can't grip them anymore

The thermal paste will not hold them on! If you want you can mix some MX-4 with some glue and glue them onto the chips, but I would just stick with the sticky thermal pads.

As for the fittings hand tight is fine, and if you used pliers that's fine as well. Just be careful not to strip the threads.

when I go to replace paste on my CPU, the heatsink is always stuck on rock solid, will that not happen to the ramsinks?

another question; after screwing on the gpu block, my gpu is sort of.. bending inwards, only 1 or 2 degrees but should I worry about that?

Some minor warping of the PCB can be considered "normal". I have had several GPU's and Mobo's warp a little without any ill-effect.

If you are concerned, you could get a (or an additional) back plate to provide more rigidity.

So long as the warping is not causing the die to lose pressure/contact you ought to good to go.
