@BonzaiDuck...1.38v is too high, hence me ordering a new chip. I've seen some really great chips so I'm hoping that, sooner or later, I'll get one. And yes, DC are 22nm.
I've got a H100i cooling my 4790K and it does a good job. My chip is no good (so I've got a new one coming) but @ 4.7GHz 1.38v temps are in the mid-high 70s
I use Sekisui #5760 thermal tape to attach the IHS to the PCB. It's so thin that it has no impact on temps and it isn't difficult to remove the IHS again if needed
I wish I had read this thread earlier. Someone mentioned that the OP should use Prime95 because the temps seem low. Running Aida64 with only stress FPU selected will do a better job than Prime95 and temps will also be higher. You may also need to bump up the vcore a notch or two.
I'm interested in either Ivy-E or Haswell-E purely for benchmarking. I'm curious to know whether the IHS will be soldered or if they will use thermal paste and glue. A chipset revision would be nice. Native USB 3.0 that works. Not so much worried about the number of SATA ports as I'll only have...
Aida64 has been my favourite for many years (even back when it was Everest) Aida64's support is first class. The other day I reported an issue with their CPUID reporting the wrong voltage. After sending them the info they requesting they sent me a new BETA version of Aida64 which fixed the...
I'm pretty sure that the trial version of Aida64 has full functionality for the stress tests. It's just the benchmarking and diagnostics that are limited. No single solution is perfect so I suggest people try a few different options and see what works best for their system. For example, if I was...
Disclaimer: This thread is not an attempt to convince people that one is better than the other. These are my results and conclusions which I wanted to share so we could discuss and hopefully learn something
Test bench:
Intel 3770K @ 4.7GHz (each test required different settings for stability)...
My new DMM arrived so I took a reading of the v-core @4.7GHz and did not see the fluctuations reported by CPU-Z, Aida64 etc. The voltage ranged from 1.236v - 1.238v. I don't feel as bad about it now.
At first CPU-Z reported 1.72v. Any lower and Aida64 failed. Then I raised the offset, lowered the LLC and increased the offset. CPU-Z reported 1.256v.
I've read this board is far from accurate when reported vcore so I've ordered a DMM.
I've set up a new test bench with an ASRock OC Formula and a 3770K. My first attempt running the chip @ 4.7GHz I had an offset of +0.010 (VID is 1.2760) LLC at Level 1 (which is the highest level on this board) The vcore jumped between 1.256v and 1.280v with an average of 1.270v as reported by...
It definitely stains but the staining doesn't appear to impact temps (well it hasn't for me) Once I de-lid my new chip and continue testing different TIMs I'm going to see if I can get the Liquid Ultra off with some metal polish. I want to avowing lapping if possible.
Wow! There's a guy on OCN who claims to have completely removed Liquid Ultra from his IHS and heatsink by using metal polish. I'm loath to pull mine apart but I'm seriously tempted to see for myself.
How long would be enough for this to happen? I've just built a test bench and will be doing lots of tests in the coming weeks so if I have a rough time frame I'll make sure I leave the H100i attached long enough so I can see for myself.
Been absent for a while and just catching up so if my question has been answered please forgive me and provide a link. I've been in discussions with people who claim that if left long enough Liquid Ultra will "fuse" with the IHS. I have never heard of this before. I am aware that it may take a...
This is exactly what prompted me to run tests between the two. There was a lot of misinformation being posted. People claimed to have used both and found Pro performed better but no one posted any results. A guy posted in Hard forums a while back that Liquid Pro was rated at 82w/mk and people...
Has anyone actually verified that Liquid Pro "soldifies" after 48 hours? I've only had it on my chip a few hours at a time while comparing it to Liquid Ultra. After my next lot of tests I'll leave Pro on and see for myself
I'm glad this was of some use to you.
I wanted to give a brief update. I thought I had applied too much Liquid Ultra for the 5GHz run so I pulled everything apart and used the smallest amount I could but still covering everything properly. I ran Aida64 for 1 hour but saw no improvement in...
Me too. It was so frustrating challenging people who had read that Pro was rated at 82w/mk and simply believed it. My thinking was, what company releases an inferior product and then goes and calls it "Ultra" It just didn't sit right. I must have filled out the "Contact Us" form on the Coollabs...
Both of these compounds out perform AS5 by a few degrees. They perform best when painted on the die of a de-lidded chip but you would still see an improvement using it in the traditional manner
Finally got a response from Coollabs...
I knew the figures that people kept quoting were not correct and now we have confirmation (from the CEO no less)
Even using it on a non de-lidded chip gives excellent results. I put it on my AMD 8150 @ 4.5GHz and got a delta temp of only 9.8c which is a fantastic result.
Exactly. So many people over there claim to have used both but not a single one of them has posted any results
To be honest, I wouldn't bother. They are so close in performance that I could have done a another round of testing and Pro came out on top. There's got to be room for error and a 3c difference doesn't leave a lot of room.
The reason I did this is because of the misinformation floating around...
I've been unable to find a comparison between these two compounds so I thought I'd compare them myself. I've had it confirmed by the CEO of Coollaboratory that Liquid Ultra is rated at 38.4w/mk and Liquid Pro is rated at 32.6w/mk.

I tried Indigo Extreme on my old 1090T and it wouldn't re-flow. Haven't tried it personally on my Intel chip but I've never seen anyone get a delta temp of under 10c with it
The title of the thread is "Best thermal compund" and the answer is Coollaboratory Liquid Pro/Ultra by a long way. Nothing comes close.
Here are the results of using it on my AMD 8150 @ 4.5GHz 1.35v with a Phanteks cooler:
Delta temp of just 9.8c. This rivals some water cooled systems
I don't use Prime to test stability and never will. Aida64 is much more reliable because it is closer to real world usage. I've lost count of the number of times I've seen people run Prime for 12 hours+ and think their system is stable only to have it crash after gaming for a while. I've found...
