Hey all, I just rebuilt my desktop with an MSI X99A SLI PLUS motherboard with a 5960X and I have the 5960X on a big custom loop with a 360x88 Monsta from Alphacool and two 120's (Two GPU's also in the loop and two ram banks)
I have come across a really strange issue where I can't seem for the life of me to get good temperatures on the CPU. I tested this setup out of the case and the 5960X could easily hit 4.7GHz on a nice low 1.31V. On the bench, I was using a 240MM AIO liquid cooler and was seeing temps of around 85C on the hottest core with Aida64 burning it in over a period of 2 hours+.
Now with the open loop and an Aqua Computer NEXT block, I'm seeing temps as high as 105C in Aida64 with the exact same voltages and BIOS settings. At first, I was thinking maybe it was an air pocket in the CPU block or something like that so I let the system bleed and kept tilting the case to ensure all the bubbles worked themselves out. After further testing, I kept having the same exact issues, so I decided to pull it apart and re-paste the CPU thinking that surely had to be the issue. Sadly it wasn't as I was getting the same results afterward. I then decided it might be an issue with pressure so I adjusted the pressure of the block on the CPU over and over with no luck there either.
After all of this, I decided it might be something wrong with the water block so I switched it out for another one that I had laying around the house which was an Enzotech Stealth with their own 2011 mounting kit. Back into windows for testing again and the SAME issues were happening, 95-105C on the hottest cores.
At this point, I started a deep investigation and concluded that maybe the CPU hold down latch was a hair above the IHS of the CPU and that it was keeping the block from making proper contact. These hold down latches are very close to the same height of these CPU's IHS's and maybe the testing I had done with the AIO's small cold plate was just small enough to fit in between the retention mechanism. So I took the machine apart again and removed the whole hold down mechanism and mounted the CPU via the pressure of the water block, now I know for a fact that the block is making contact with the IHS because the system is able to post and work fine. I know the CPU has to have a fair amount of pressure on it to even make good contact with the pins so now I know for a fact the IHS has contact with the water block.
Booted into windows again only to find out the same issues were happening again....
I am at a loss as I have absolutely no idea how this could even be possible for me to be getting such a high temp with such a low voltage on a big open loop with high-end water blocks. Not to mention how well it did with a freaking 240MM AIO cooler.
Some final things to mention
-My two GTX 1080 Ti's both sit in the low 40C range during stress testing them, so they're acting normal-
-I'm monitoring my coolant temperatures and they are all perfectly acceptable in the 32-36C range-
-I'm also monitoring my coolant flow with an Aqua Computer flow meter hooked up to my Aqua Computer Aquaero 5 Pro, the pump is moving coolant just fine-
Thank you in advance for any advice.
