  1. Corsair, I don't know why you have a video guide of your pro block going in the wrong orientation of the fins/cold plate of the new Alderlake chips.
  2. So an update. The EK Velocity 2 completely fixed the issues I was having. The cpu at 5.2ghz/4.1 on a 30 minute r23 loop peak at 86c. Before I couldn't even run the benchmark with an xc7 without a BSOD. It 100% was not a mounting pressure issue. I would suspect more of an orientation issue of the cold plate. Its crucial the cold plate aligns with the 12th gen die. If the corsair logo is facing the bottom, you are 100% making contact with 70% of the die on the fins/more surface area of the cold plate.
  3. I submitted a ticket and get a robot response back by a corsair rep. I follow up to zero response. Its very simple really, the valve I ordered doesn't appear to close all the way and drips actually occur. It sits like \ instead of | when "closed" I literally broke a wing off trying to force it to close and be straight. Its brand new within the last 2 weeks. I have a plug in the end it just looks janky in a way. There was this and the jig that comes with the corsair tube bending kit that easily scuffs or marks the tubing. Even more so when paired with the dollar store hack saw that come with it. Marked a lot of my material
  4. If that were the case my arctic freezer would have performed poorly on my strix d4 board. It has the cut outs for the 1151 socket and seems to work fine with it. The 12900K is an extremely hot chip but honestly the temps are really bad with this block vs my arctic freezer II. Just search xc7 pro reddit and you will see some complaints about that block too.
  5. They did but if you look on reddit you will see people posting nothing but issues with that block. I don't even see it available anymore meaning maybe they halted production.
  6. In time I will know. When I removed the washer mod it seems even at 5.0ghz the temps are now worse. I believe it was actually doing something and the spread of the paste looked good when I removed it. I ordered an EK velocity 2 and I will update this thread with results.
  7. I believe what the issue is possibly the die of the 12900K is longer top to bottom. The way I have the XC7 positioned is with the cold plate/logo sideways as if it were for older 115x. So basically its possible the outside cores are getting warm because the IHS isn't making 100% contact with the fins on the block. I am contemplating just ordering an EK block that's designed for 12th gen that I know for a fact makes proper contact regardless of the washer mod.
  8. at 1.3V pulling 240W at 5.1/4.0 in R20 the CPU hits 100C in a few seconds. I removed the washer mod with zero difference in performance.
  9. All in all its sad to see the xc7/pro have a lot of issues cooling the 12900K. Yeah -5c in the loop with 50 more watts in the GPU 400 oc vs 350 also 1000mhz on the vram.
  10. The photo just looks misleading. Theres a 90 going down and a 90 going up. A tube from the xd5 to the bottom rad, other port to the back of the gpu to the 90 going up to the cpu. My aio was making poor contact on the bottom of the cpu and thats why I went with the washer mod. I definitely dont think its a mounting pressure issue and majority of people having issues with the xc7/xc7 pro did the mod to fix performance issues. I think the block just isn't the greatest and I will probanly just order an EK block. I dropped my coolant temps nicely just by removing the dust covers in the Lian Li 011. Its like they were just trapping the hot air in, you could feel a huge difference of air flow after removing them. Averaging 35-36c on the coolant now.
  11. I ordered the XH305i because it was on sale on Amazon and the price was actually cheaper than ordering things individually. First off, I have to say that the bending kit is trash. The hacksaw cuts like garbage and the jig scratches the tubes very easily causing me to order new ones from Corsair. No clear, so satin clear. This actually really annoyed me as Corsair uses the worst shipping company in existence, USPS. Anyways Through all of it the XD5 pump seems to have some like adhesive on the bottom and Amazon will do a exchange for the kit but honestly its a lot of work sending it back. Draining the loop, taking rads out ect. I ordered a second rad and paired them with noctua fans. https://imgur.com/a/qAkovdi My question is, the 12900K seems to hit 100c in a few seconds of Cinebench at 5.1GHZ. I don't believe the XC7 is making bad contact, I even did the washer mod prior to the loop. Under normal game loads the CPU stays around 60-70 stable and passes P95. When gaming in GOW at 2880x1620 (the dldsr 4k res) the Vram hits 64c max, core 60 on the GPU, CPU hits 75C and the coolant temp his about 41C. Is this a good temp for the coolant in a loop like this? or is my pump maybe faulty? at 3500 RPM it makes a bad noise but seems fine at every other RPM/higher RPM.
