Water chiller... what have I ordered...

Isn't the way the condensation is lit up by RGB beautiful?

looks like you need some of this

Carefull.

 

Condensation can occure inside the CPU socket itself if things get to cold.

Also the block has an overhang, over the IHS, where condnesation will form.

 

if you are going to continue with condensation at levels in the pics, you really should take the system apart and apply 'proper' condensation protection.

Initial results:

 

Y-cruncher (AVX-512) - previous watercooling got me to 4.3 needing 1.225v for stability. With chiller, I already forgot what voltage I needed to get 4.4 stable-enough, but 4.5 wasn't having any of it and CPU temps were already into the 80's at that point. I didn't undo some limits in bios at this point, so it might be worth a revisit.

 

Cinebench R15 - previous watercooling got me to 4.9 at 1.35v. With some bios tweaks, I was able to run 5.0 at 1.40v. 5.1 wasn't happening. Temps again were well into the 80's.

 

I was able to improve times on the above two but 100 MHz isn't much. I also had a quick go at Cinebench R11.5 but wasn't able to beat my previous sub at 4.9.

 

Because liquid metal solidifies at low temps, I had swapped to Kryonaut under and over the IHS. I was generous in application, but I always have concern about if it might have pumped out especially as I had to slide the IHS back into position when fitting it into socket, so could some have pumped out? Min-max core delta under load was ball park 13C.

 

So I could re-apply Kryonaut in case I had pump out. Another alternative is to go back to liquid metal, but limit the chiller to ~11C or so to prevent LM freezing. It'll be an interesting tradeoff... cooler liquid temps but worse TIM, or warmer liquid better TIM.

 

As for the chiller, set to 2C target temp, it never reached it and turned off. It was close, but not quite making it, especially once I turned on the PC, then floating around 3 to 4C. It might be more energy efficient of me to regulate to 6C, so I lose a few degrees but I'm not draining 500W in the background and dumping it into my room continuously... if I went for the warmer water + LM route, this would obviously not be a problem.

It's only for benching, not going to run 24/7. Done enough for one day now and need to have a think about improving the setup.

It's a shame Boyu dont sell their R22 variety of chillers (CW and LN series) in the UK, those would be good candidates for subzero modding.

 

The only R22 chillers i know that can be found in the UK, is the Healia HC1000B, HC1000BH, and HC2000BH. All of which you have the specificaly ask the retailer which version they have, as most of the time even they dont know of hand and have to check physicaly what refrigerant is used in their stock. Usualy if a place has a HC1000 in stock, its the HC1000A which is r134a.

Liqud metal doesnt go solid. it just cracks and your cpu dies

Not a good thing either way 

 

Since it sounds like you're in way deeper than I am, are there any UK OC events as such? Be interested to see LN2 use in person.

just booted my updated system, pretty happy that i have a desktop again, then i lulled at the idle temps

there was quite a few last year, but there hasnt been one since earlier this year. there could be one during the country cup though.

First just wondering if you have seen the folding event coming up

 

 

New badges are  coming!!! 

 

Also damnnn, you have too much money on your hands! I hope you enjoy playing with your new toy!

I hadn't... but... new badge!

 

I don't do folding much these days. GPUs run way too hot for 24/7. Let's see what the weather does, although I'll try to put at least one system on 24/7 for it.

It's all relative. People prioritise different things in life. This is one of mine currently.

Sounds good man!

 

Also I guess so, I say the same I live on benefits and have a kickass system, people say Im wasting my money. But I dont smoke, dont really drink so this is my guilty pleasure.

Sorry to dig out an old thread.

 

Is the chiller worth it in the end?

 

I'm considering getting the one from AlphaCool for benchmarking purposes.

For benchmarking, on average I'd say running this chiller just above freezing gives me an average 100 MHz over regular water. Is it worth it? For just some benching, I have to wonder if it would have been a lot cheaper just to produce ice on scale and use that to cool a loop in short term.

 

At the time I bought it, I had more money than I know what to spend it on. It provided some fun for that. Apart from some benches I hardly used the chiller and have actually listed it on an aquarium sale site trying to shift it. No bites. Just want the space back at this point.

[AnonymousGuy]

I've been down this road too: it's not worth it.  At least on all current Intel stuff you're going to hit a silicon limit before you hit a thermal limit when you're watercooling.  I tried something like 1.7V with a 7700K and it couldn't get > 5.3Ghz stable which was fine at like 1.55V.  Not to mention the power consumption of chillers is bonkers and they make a bunch of noise.

Thank you very much. Always water a chiller, but I guess you need TEC for higher frequencies.

You need phase change, cascade or LN to really make it worth it.

 

Or start with dry ice at least…
