Best perfomance cpu water block

[PWforPower]

Is there any performance best cpu water block for am4 which can hold - 30C° ? 

[Grabhanem]

Maintaining 30C on Ryzen is extremely difficult, as even if you can keep the waterblock perfectly at ambient you'll lose quite a bit of temperature from the thermal resistance of the IHS and thermal paste. Under load it would almost certainly require exotic cooling like ice buckets or chillers.

 

Is there a reason you need that temperature in particular?

what type of cooling do you have in mind?

[Enderman]

At -30C your fluid will be frozen.

For sub-0 temps you need to use a phase change cooler with an evaporator head, not a waterblock.

For -30c you don't use a waterblock

I have custom mini 600w glycol chiller, I have loop for gpus but I dont know which cpu block to use that can hold

- 30C° liquid fluing trough.

Do you mean ~30C (around 30C) or -30C (subzero)?

The limitation  won't really be the block per se since as long as the coolant is liquid and the pump is powerful enough. Its good to keep in mind that viscosity increases with lower temperatures and a CPU waterblock with microfins are quite restrictive. Any modern CPU waterblock are within a couple of degrees of each other. But its definitely good to keep in mind that if you coolant is only -30C, your CPU will definitely not be at -30.

Well since no waterblock is tested for that occasion because well ya know these are meant to go into positive temperature environments I'd say any decent quality one that is just metal and without electronics could possibly work. You'd mainly want to look for ones with bigger and more spaced out fins due to the liquid you use and the temps you are at.

I'm sorry, I won't cpu at -30, _30 fluid will flows* trough.

Still same story for -30c liquids. A waterblock is not made with those in mind so really they will all not be great for your purpose.

No no, I know that, I'm so sorry because you didn't understand me. 

My exact Question is which cpu block can hold -30 fliud flows trough without interruptions.

What is your exact coolant, and what pump are you using, more exactly, what flowrate can you achieve at -30

Ethylene glycol has like 20x higher viscosity than water, that's not gonna flow through the microfins inside a CPU block.

 

Also why do you think your chiller goes to -30C when most chillers are only rated to -5 or -15C before freezing?

[PWforPower]

I asked more precisely for the block with the highest cooling capacity at water vicosity let's say, all the other is to mine.  Forget about - 30, I just asked expecting someone has already searched for an answer on google, to save my hours by searching for an answer.

 

But however thank you for discussing.
