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 😞 )

So this is my first custom loop build. I wanted to go custom to decrease noise and to give myself the ability to watercool the board vrm since it came with a waterblock, and the GPU in the future. CPU itself can draw 300W under load so to cool everything in one loop, I need quite a bit of cooling power. I started looking into the surface area of different size radiators and determined that a 400mm rad is the probably the sweet spot. The 400mm rad has more surface area than a 560 rad, and I only have to buy half the amount of fans. My main concern was the fact that 200mm fans usually have low static pressure, but I found a solution to that. For Science! gave me a link for a high static pressure version of the noctua nfa-20 fans that are not listed for sale on noctua's website, so big thanks for that. Finally got all the parts in and built. After testing, I found the temps to be within only few degrees of my previous setup, but that is with the vrm included in the loop, so I'm fairly certain the temps should be lower without that. At idle, the coolant temp sits right around ambient. Also the max fan rpm has gone down from 3000 with the previous setup, to 1200 so the noise difference is incredible. I went with soft tubing & barbs for now because the system is on a test bench, so who cares. The cable management is terrible, I just have everything set up for testing. Not sure if I could fit this into a case, but for now I like it sitting next to the bench. The size of this thing sitting on the desk is hilarious to me. Wasn't able to find many custom loop 400mm builds online so I wanted to share this.

I see that you are a man of culture
Thought it was gonna be a generic rgb loop in the first half
 
Though why an open bench setup? Not exactly common to daily just because of aesthetics or the mess it makes, though im also a proud user of open bench, just a tad more crude 😉

 
Also 400mm for all i know is not a common pc rad size, whered you even get the thing?
 
 
Ive also been trying to make a ghetto loop of sorts but i am just extremely lazy and making slow asf progress, i do have all the tools and hopefully my adhesive problems are solved now that i have epoxy instead of just superglue, only reason im building this is just to overclock the balls off my 775 and 1366 cpus because 5ghz e8400 go brrrrrr

Heres the pile of garbage in near its current state
 
Btw you may wanna put a fan over those rams, 1.5v is pretty much the max w/o fan due to heat and b die is ideally run at 1.6v+ (b die does not degrade with voltage), only equivalent i have to fast rams is just some team extreem dark ddr2 1066c6 1x3 thats been oced to 1520 7-9-6-9 2.38v (very very fast for its time, still crushed by micron d9s) and all my ddr3 sticks that do 2200+ (x5660 cant handle 2200+), maybe some time in the future ill make a chiller for my rams

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 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, 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.

Hi, this is my crosshair viii hero with the watercool chipset block...

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

Watercool HEATKILLER (NSB or SB)
 
I think you have to order direct. I can't find any in stock, and some places report 30 to 90 days out. But because they're a reseller, they're just waiting on their own shipments. I suspect anyways.
 
Also, ideally you'll want the SB (South Bridge), but NSB (North South Bridge) will work too, you'll just have to validate obstruction with the video card.
 
 

i recall d5 next pump has both temp & flow sensor
a bit on the pricey side though 😅

This time its the right test and all cores enabled. 2 passes in 2h looks a lot better😁

Tomorrow I try the new memtest86 and this time with all cores enabled 😀

10 passes, ouch. I ran 2 passes, the first took 2h 50 min, the second nearly 9h. After 12h of memtest i thought it would be enough😥

I thought one ddc should be sufficient, so why create another point of possible failure and noise? But in the terms of overkill, you're right.👍

Y'all are amateurs for not knowing about multiport radiators that would have let you run a normal radiator in that space.   http://www.xs-pc.com/radiators-ex-series/ex240-multiport-radiator
 
And use some quick disconnects so you can fill it up, detach, then reattach to the actual loop.  Wasting effort designing a reservoir to solve what is nonissue if you know what you're doing.  (and lets be honest anything Alex designs/builds is probably going to leak anyways)

Good fittings from bitspower, good radiators from HWLabs.
 
They basically failed on the only thing they actually sourced themselves. Should have also sourced the blocks from EK or Watercool

Hi Everyone,
 
This topic is meant as a sanity check.
 
In my current situation, my PC is in a room upstairs. It already runs a custom loop. Since I’ve discovered steam remote play, I’ve been using it more and more. On top of that, my SO likes the fact that I’m more downstairs.
But steam remote play has its limitations, so I’ve decided that the next PC will be built for the living room near the TV. Because space is limited, this new to be build PC will be water cooled.
 
And that is where the passive part comes into play. Last year, we renovated your house. Because of this, we now only use our in floor heating system. So I have a heat exchanger near the TV with no function.
That’s why the idea was born to use it to passively cool the new PC.

The brand is Jaga and it has the following specs:
 
The design description by Jaga:
The Low-H2O heat exchanger consists of round seamless circulation pipes of pure red copper, fins of pure aluminium and 2 brass collectors for left or right single-sided connection 1/2”. Extended air vent 1/8" and drain plug 1/2" included.
 
A drawing with cross-section:
 


Dimensions of my heat exchanger are 240cm long, 20cm high and 11.5cm deep
 
Dissipation power:
With a water temp of 35˚ C it radiates 219 Watts passive
With a water temp of 45˚ C it radiates 508 Watts passive
With a water temp of 55˚ C it radiates 757 Watts passive
With a water temp of 75˚ C it radiates 1572 Watts passive
 
This is with a room temp of 20˚ C

PC spec wise, I’m still waiting for ZEN 3 and RDNA2/Ampere so let’s say it will most likely be equivalent to a 3700X and a 2080 Super in power consumption.
 
The pump I will be using for this is an EKWB dual D5 with PWM.

So what do you guys think? 

I you need any extra info, please ask.
 
Kind regards,

Hey everyone,
 
because of some occasionally post problems (F9 -> 0d) I tried some different bios settings. For this score I increased the cpu speed to 4.4 GHz at 1.32 V all core, but I reduced the memory clock to 3466 and set the timings to 14-14-14-34. The soc voltage is now at 1.08 volts and vddg at 0.950 V. I hope these settings are stable....

Looks interesting, grüße aus dem Saarland :D.

Hi, I set vcore to 1.3125V, load line to level 4, soc voltage 1.10V and the dram voltage to 1.36V. I increased the vcore voltage from 1.3000 to 1.3125V because it bootlooped one time after a restart, but I had no errors when running benchmarks and playing a game. Also I ran cinebench with realtime priority in task manager. With normal priority the score was abaout 100 points less.
 
Edti: increasing the vcore a bit didn't help, it still doesn't like restarts. But what confuses me is that it doesn't bootloop on every restarts.

And here is my R20 result.

Even though they will be receiving a high end gaming PC, I really feel sorry for the third ROG Rig Reboot winner who has to follow this act ?

yeah but at the same time

it creates a bit of a disconnect with the actual variance. In this video it would be more accurate to show that the results are very similar rather than one being superior, as there is actually little variance and therefore the gaps in the results are a bit artificial.

Success!
