    Hi together, I want to share with you my experiences with the Thermal Grizzly Kryosheet, a graphen thermal pad in combination with a Watercool Heatkiller V waterblock. I recently upgraded my system to a 7800x3d and an Asus RTX 4090 and heard some stories about the fast pumpout effect of thermal pastes on the GPU because of the very high power consumption and therefore high heat generation. So I tried the graphen pad, and I think the results are acceptable. I also couldn't find any information about the dimensions of the AD102 die (it's around 24x26,6 mm), only the die area of 608mm². I used the 33x33 mm pad and protected the SMD's around the die with kapton tape. These are some pictures of the gpu and my 3DMark Timespy result (don't have a key for Port Royal or Extreme )

    I'm a little confused, where are the 5°C temperature and the 2000 RPM decrease mentioned in the video?

    Hi, this is my setup: Dual Aquacomputer D5 Next with an Watercool Dual D5 Top and 2x Mo-Ra3 360 + XSPC RX360V3 combined with a stainless steel plate heat exchanger and another Mo-Ra 3 360 in my basement. edit: added a better picture of the dual pump.

    Hi, I would say yes, a that a D5 can handle such a loop. Are you pointing with your finger on the pump and is the pump mounted upside down? D5 pumps should not be operated upside down...

    "Did you notice performance improvements with the drop in temps? " unfortunately not much. I think the gpu clock stays now more stable between 2085 and 2100 MHz. It's currently around 16°C in our attic, maybe this isn't cold enough... For connection, I used some G3/4 brass caps and drilled G1/4 threadings inside them.

    Hi together, I just want to share my recent wc loop upgrade with you. My previous build log can you see here: I used a plate heat exchanger to connect a second cooling loop to improve the cooling capacity. I used insulated soft tubing to connect the secondary side of the pwt to a Mo-Ra 3 360 in our unheated, but insulated attic. Now the water temperature stays at ambient, or 1°C above when playing Cyberpunk 2077 and the system puling aroung 400 - 450 W power. I'm planning to cool my PC and the room it is in with some underground geothermal collectors for the next summer :D.

    Hi, thanks, i read this ,but I'm looking for some personal experience with these pumps. I already own a Aquacomputer D5 next.

    Hi together, I'm interested in buying a DDC Pump, one with PWM control and want to ask if someone have some experience with these pumps. 1: Are they reliable? 2: Do they actually need active cooling under their pcb? 3: Do heavy brass tops really reduce vibrations (like the Alphacool Eisdecke, or the one from Phobya)? 4: Is the flow rate higher compared to a D5 at the same noise level? For the active cooling aspect, I thought of buying a chunk of copper, drill some holes in it with G 1/4 threads and connect the pump bottom case in my cooling loop.

    Hi, I use 2 Mo-Ra 3 360's and I think there will be no real benefit to change the radiator (maybe 1 - 2°C difference). But imho the build quality of the Mo-Ra is better....

    Thanks @jonnyGURU, I wasn't sure about that. The TEC's should support my existing loop to reach slightly sub ambient temperatures and are cooled by their own loop.

    Hi all, I want to start some experiments with TEC- modules. I bought some pci-e 6-pin extension cables to power the 2 TEC's and now I want to ask if it is safe to solder the 3 (2) 12v cables and the 2 ground cables with the sense pin together. I heard that the sense pin is just another ground connection, but I don't want to blow up my psu. It's a seasonic prime 1000W.

    Hi, if you have a local glass manufacturer in your area, you might get the tubes really cheap, even angled ones. I would recommend using petg first as a template and then cut the glass. I used the same tool as jayztwocents did, but without the drill. You can do some small adjustments with a diamond cutting wheel if needed, just be careful with the glass dust. Imho glass looks the best and you don't get problems with any coolant you would normally use in a pc.

    But I don't know why, the temperatures seem to be fine.

    Hi together, I recently tried to run a blender benchmark as I did a few weeks before and i am now getting weird restarts with the error message below. My CPU temperatures during blender are in the high 70s to low 80s according to HWinfo64, and the overclock was stable so far. 4.35 GHz @ 1.31V. Could this be a sign of degradation, or is there something wrong with the bios (bug?). First time i ran blender I was on bios version 1201, now I use version 2204. But even 2204 was stable, since I use it since 2 months now...

    Hi, i use one of these on my Crosshair viii hero: https://shop.watercool.de/epages/WatercooleK.sf/de_DE/?ObjectPath=/Shops/WatercooleK/Products/10204

    Hi, I use this one, but I don't know if you can connect it directly to the mainboard: https://shop.aquacomputer.de/product_info.php?products_id=2294
  17. B4Quattro
    Ok, I didn't know if these timings are any good. I tried to keep the vcore under 1.32 because I'm a little afraid of degradation...

    Hi all, I wonder if these are decent render times and temperatures for a watercooled Ryzen 9 3950x?
  19. B4Quattro
    This the vcore my 3950x drops to during cinebench r20 and PBo enabled. Normaly I set it to 4.35 GHz and 1.32v which drops to 1.28v under load.
  20. B4Quattro
    Try enabling PBO with auto vcore and run a stress test. The voltage the cpu drops to should be the safe voltage for that specific chip.

    I think if you don't get errors during 4 passes it shouldt be fine. Somebody said if you don't have errors after 10 passes you are completely safe. I did 2 passes with memtest86+ (12h with 1 core ) and 4 passes with memtest86 (all cores, another 12,5h) without errors and I think this is enough for me
  22. B4Quattro
    This time its the right test and all cores enabled. 2 passes in 2h looks a lot better
  23. B4Quattro
    Tomorrow I try the new memtest86 and this time with all cores enabled
  24. B4Quattro
    My fault, I used memtest86+ instead of memtest86. Seems to be a different programm.

    I have 64GB ram and its version 5.31b
