hey
right now i used MX-4 on my cpu and i heard very good reviews about the Coollaboratory Liquid Ultra thermal paste how does it work?is there any BIG difference drop in temps?does this thermal paste can do anything bad to the cpu itself?

You apply it like normal thermals, but abit more carefully (They give you a brush to spread it with so use that) you dont use dot or line method to apply it you cover the entire cpu with a thin layer. It gave me a 10~20?c temp diff vs. AS5 when getting into higher clocks... Considering MX4 temps are just about the same as AS5 CLU would benefit temps a decent amount.

To give it an example, CLU is much much better.

Thermal Conductivity (W/mk): 8.5 (MX4) 38.4w/mk (CLU)

whats the difference?
Pro has less w/mk, Ultra is newer and supposed to be better and easier to remove and apply. Though, Pro is said to sometimes give slightly better temps (nothing radical from ultra they are in same playing field maybe a 1~3c offset).... but removing Pro can be hell on earth.

What you linked for 7.99 was TIM Thermal pads xD dont use that.

With Ultra, yeah itll be simple. Pro was the one that was a fight to the death.

When applying it do i have to wait a couple of seconds/minutes and then mount my cooler on it?or after applying i can instantly mount the cooler?

You can mount right after you apply it

I want to add for anyone else that I added this to my two 670's and the temps dropped by around 7 degrees celcius, from 70 degrees under load to around 62-63.. amazing stuff, just don't use it with aluminium.

Just to let you know CLU has the potential to do something like this to your copper block on the H100. After a little time it will "weld" itself to the copper block and may corrode it a bit. After an extended amount of time you might have to apply a good amount of pressure to the block to get it off the CPU and then spend a little time sanding the block down to get rid of it. I personally only use CLU on my die for that reason. I use mx4 because IMO the hassle of getting it off isn't worth the extra 3c-5c extra drop I would get if I used it on the IHS and block.

Fairly certain only CLP does that.. are you sure its CLU? from the clumps it definitely looks like CLP.

I'm glad you helped this guy out, seems some other people here were letting him think you can use CLU on anything and it will "just give you better temps"

im almost sure CLP and CLU is made for dies like your cpu die and gpu die while using it on a aluminum/copper heatsink for long periods of time is going to give you a weld effect which you will have a very fun time removing

What happens with aluminium heatsinks is that it EATS them basically and also coollab has also warned against using it but surely there are people who will do the sheer opposite.
Applying this on the stock intel heatsink

Not him though, i mean some idiots

I took off my heatsink on my 670 to have a look, and it seems to be looking fine. Its been on for around 2 weeks now I think. The heatsink itself is aluminium, but the part that its on is copper (Its on the heatpipes which touch the GPU obviously.). No part of it touches the aluminium heatsink, so I think its gonna be fine. Ultra is ALOT easier to get rid of than Pro. I've used pro, and it makes horrible clumps that is almost impossible to remove.

if i remember right, ive used this pic myself a while ago,
what you see here is clp/clu on aluminium, not on copper..
youre right about the welding from CLP to the block, but it wont eat the copper

My CLU isn't forming clumps like that, nor is it looking like its welding so far.. maybe long term effects maybe?
