Will that not leave an air gap between the Copper Top and the CPU PCB for Frost to build up?

Got it, Thanks
My supply cabinet is filling up now 

I'm not convinced that bullet is worth biting atm... Johnksss HC dripped water all over his rig... I have multiples of EK & Heatkiller VGA blocks and non of them have ever done that.
 
Sometimes products from great companies miss the mark.

Random question for those that are sub-zero cooling, what brand of thermometer are you guys using? Any recommendations? I know Flukes are good but their price tags aren’t good lol Also not sure all can read temps for anything below -40ish C? I see some on Amazon for like 20-30 bucks but I’m not sure if they read accurately or are reliable

Gotcha. So is the accuracy more in the type of probe used or the thermometer itself?? From my understanding all K-types will be good for anything down to -200C regardless of thermometer. Or do both matter?

This was also my understanding. But now I know either the Thermometer or the K-type is not suffecient for the task at hand.

I am now seeing the GPU PCB Temperatures running closer to MEM1 @ 42°C and 44°C @ 99% Load pushing 330 Watts non-stop for the last few days.
Peeking at 400+ Watts as shown in one of the Images Below.
Running Moo! Really Pushing the Graphics Card Overall the Computer is pushing just under 590 Watts using Only the GPU, no CPU Tasks Running.
Pushing a Solid 2040MHz 1.050 Volts and 99% Utilization
Maybe the KPE Hydro Copper Water Block just need a little longer Break-In Time. GPU1 39°C & GPU2 40°C Coolant @ 26°C Flow 3.7 LPM Room 21°C
Flow is from the Out on the GPU so I guess I could test the Flow going into the GPU to see the Difference if any. The Flow is the Same.
It is not about how high or low but how close they are together now as before the GPU PCB Temp was 40°C and MEM1 was 50°C or so.
Using a Standard Custom Water Loop, Separate from the CPU Custom Water Loop.
I added a Flow Meter and a Coolant Temperature Sensor.

Okay. Base on the OCN forums there’s a PerfectPrime Thermometer for 32 bucks that people have reported will read down to -200 with the right probes. Think I’ll give that thermo a shot and pick up some Kingpin k-type probes when I buy my Tek-9 icon. I think I’ve found my max performance with my stock cooler and am ready to get frosty. Great scores btw Zedd!! Was that with LN2 or DICE?

Thx. I am kinda using the 9900k/z390 platform as a lab but will go pretty hard on 7/7. Pretty much no end in sight for me and benching . If I don't like Zen 2 Ill move onto this years HEDT ect... Maybe SLI but I was hedging that SLI was dieing and it looked that way until a couple cheaters started using software to quad SLI on the HOFS
 
 
I have that PerfectPrime & only Chilled water and dice so far.

How’s the Tek-9 for DICE? And what alcohol are you using for your medium? I’ve been thinking of using methanol, just gotta find a supplier

Lmfao, wouldn't you be better off with a test bench instead of a case? Barely any of that loop is in the case.

For DICE acetone works really well and is available @ a lot of stores. Store the DICE in a Yeti Tundra 50.
 

Dry Ice rated and stores 30lbs for 5-7 days easy. I did not believe it untel I tried it. I still have 5lbs of dice in it from the last bench session and bought the 30lbs of dice on 6/15/19. Though that remaining 5 lbs has H20 ice around the edges and without chizzling it off should not be used... Don't want H20 in the pot.
 
@bcav to be clear. I was not down at -140c that is not possible with dry ice. But cold bugs and TIM failures surface from 110c to 140c. I just do everything with LN2 in mind regarding prep because that is what should be used if one is not a "chicken clocker" like my self. But hey I am almost ready!
Will only be able to get that cold with LN2 or another colder liquid brought to boiling point in the pots.

Front are exhaust, no filter on front, top are intake filter on top and rear are intake no filter.

The Cost is High for Fujipoly 12 W/mK Thermal Pads and seems you can only use them Once and then they fall apart.

So I am staying away from them.

Good reviews here
mod/smart Fujipoly Ultra Extreme XR-m Thermal Pad - 60 x 50 x 0.5 - Thermal Conductivity 17.0 W/mK
The ones in the know, which is you the reader of this review, love this stuff. Fujipoly Sarcon is the mythical 17W/mK stuff that's incredibly fragile yet somehow pulls heat off of hot mosfets and chips like no other thermal pad/putty out there. It's not conductive, stays put, doesn't dry out, it's the trifecta. It doesn't have the properties of the Panasonic soft PGS where it spreads out the heat, this stuff fills in gaps and transfers heat away. When you need that little extra bit of headroom because of a heat issue, this is what you need.

We have asked this question a few times now but no one is responding "How thick are the pads?"
100 x 15 x ?.0 is the size you can but and will cost you.
You will need
4 Each 15mm x 55mm (just short with one strip for 2)
1 Each 15mm x 100mm
1 Each 15mm x 25mm
1 Each 7mm x 115 mm
1 Each 7mm x 50mm
2 Each 10mm x 10mm

Thanks sir. It had some real hate for the pads in the past (but still kept using them.) When i got them before they were it some super ghetto packaging (like between thin cardboard) and dry. (2016 vs 2018)
But the ones for my Titan RTX SLI and my 2080 ti FE SLI were not. They where in real packaging too. They were puddy-like.
They are packaged by primochill now. (at least the ones i got off amazon that i'm really happy with.)
 
I'm thinking i'll just of the ram? which one is that?
