No im only chilling rams and vram because theyre lower power draw and usually yeild the most benifit vs cpu and gpu core oc, something that i can daily pretty much rather than have a freaking ac unit chiller consuming craptons of power with negligable oc benifits since phase is the way to go for core oc and i dont have any experience nor the equipment neccesary to work on these ac systems if that isnt obvious already

 

Fridge just because for whatever reason (prob hygene or something) used fridges tend to not sell well and i can get one for <40$ pretty easily

 

Damn, and gpus have how many of those damn chips again? Like 8? 16? Yea thats alotta power, i thought they were gonna be relatively easy to cool but apparently not, though with the amount of liquid id need to submerge a damn fridge evap to make a chiller itd prob not matter due to the thermal mass of the craploads of antifreeze so spike in power draw wont matter, maybe full load but again crap tons of thermal mass to heat up

 

I only recently figured out thats the reason why res are reccomended for custom loops, more thermal mass = more time it takes to heat up and cool down so basically like a regulator and why i see some posts about absurd temp spikes on load with even a 360 aio. Guess its like a flywheel on a car, though i wonder if less thermal mass has any benifit here cause lighter flywheel = faster acceleration but more deceleration when letting off the throttle

Im not certain but it remember that gddr5 could go up to like 4w a chip which honestly is a TON of power. More than some current day mobile cpu's

 

That trend has not gone down and gddr6 and 6x as well as gddr5x can consume more.

 

So yeah pretty much tells you why it needs cooling

Also, I thought about the drain plug and wont is be harder to do with soft tubing?

And stuff like the little screen that show coolant temp I don't really see those used in s soft tubing loop

You have some examples?

Its really confusing with US and EU units of measurement

i be leave you want the (16mm or 5/8 od) and (12mm/13mm  or 1/2 id) that would get you 3 to 4mm and 4mm is 1/8

2mm would be 1/16

 

16mm - 12mm = 4mm

16mm - 13mm = 3mm

 

i messed up buying the wrong tubing 2 times... before..

Gonna be so much easier with soft tubing to attach a tube to drain the loop. Even in hard tubing loops the drain tube is usually soft tubing.

 

Nothing is stopping you from adsing a flow meter or coolant screen. Those have nothing to do with tubing.

Temp spikes dont have much to do with the thermal mass of the water but with the thermal mass of the block and the rate it can exchange heat with the water.

 

The waterblock is a heat exchanger flat out and if that gets overwhelmed by either recieving more heat than it can transfer or the water not being able to keep up with the needed heat transfer you get big temp spikes and overheating whilst the coolant stays not too warm.

 

The 12900k is an extreme example of overwhelming almost anything. It needs great thermal mass, a massive temp difference or highly efficient temp transfer.

*laughs in direct water to die

I do wonder if direct water to die would help a 12900k

Doubt it. Its just an insanely hot cpu when allowed to do its thing

Well ig if it did need direct die it wouldnt be benifiting from extra cooling like my e8400 (garbage die to ihs heat transfer even though its supposed to be soldered)

Ooh I misunderstood. Yeah direct can help but Ibdoubt it will do much as the contact plate is thr problem here. As the contact plate with the fins that exchange heat with the water is what has trouble keeping up. So adding even more efficient exchange of energy would most likely just result in quicker overloading.
