post #29081 of 33991
I have a 2009 Mac Pro, they come from the factory with delidded CPUs. Would MX-4 or Liquid Ultra be better on the die. I know that MX-4 is said to last up to 8 years. I would like something that at least last 2-3 years before I need to reapply, I cannot find any info anywhere that shows how long Liquid Ultra usually last before it needs to be reapplied. Since you can't really overclock a Mac I am not too worried all that much about 3-5 degree variance in temps between the thermal paste as the temps shouldn't be that high to begin with even under load. I have a tube of MX-4 already and have used it in multiple builds, no experience with Liquid Ultra though. I am leaning towards MX-4 since I already have it and know it works, also for the safety of being non-conductive.

Search function "pump out" in this thread. Using any non liquid metal will eventually lead to a drop off in performance after a numher of thermal cycles. That means that reapplication is needed more frequently than every three years. The only real solution in my mind is for you to use CLP or CLU.

Thanks, I actually just came across an article on anandtech showing a shootout between 3-4 thermal paste and it concluded what you are saying. I guess I will be picking up some CLU off Amazon.

I did a trial run last night on an i7 960, I will test it in the next day or two. If she survived then it will be on to delidding my two X5690s.

Any preference of CLP or CLU over the other?

I was also going to just use clear enamel fingernail polish for the caps. I guess that will suffice or is there better alternatives to coat it with.

I'm using CLP and CLU are rather similar. Though CLU is supposedly easier to spread, and CLP cleans up easier.

I sold my CPU. I need to remove the CLU on the die.

Two questions:

1) How do i remove it without ruining something?¿
2) Should i expect any resistance while trying to remove the IHS after 2 years of use without touching the CLU on the die? Don't want to break the die.

Clean with 91% Isopropyl Alcohol, and be thorough. I use an LED light to check for any tiny drops of the liquid metal that may have wandered off.

The CLU should still be soft, so I wouldn't expect much resistance when pulling the IHS off. thumb.gif

I created a custom delidding vise. Yeah, it's over-engineering... but I'm an engineer... it's what I do. No risk of damage from clamping in vise and no projectile CPU.

What would you guys say is the max vcore to push through the chip?
Can I be added to the club.

I need the info required from the OP. that way I can enter you in! thumb.gif

That looks awesome.

OCN name: v1ral
CPU: 4790k
on die-TIM: Thermal Grizzly Kryonaut
ihs-TIM: Thermal Grizzly Kryonaut
Mhz gained: Unknown ~200mhz
OC after delid: 4.8 Ghz
Temp drops: 5-7c
CPU-Z validation of max OC:


This is a rushed submission:)

I will be retesting when I get my CLU in the mail, hopefully dropping temps even more.
