liquid Consistent Subambient Cooling

[TechSwagPimp1337]

TWMC,

 

I’ve always had really high ambient temperatures in my room during summers. It was refinished from an attic storage room, and I live in the south.

 

I’ve tried air coolers and AiO’s to cool the CPU, but in summers, I hit around 90°C max on my CPU. I’ve decided to buy an active chiller to reduce my temps down to something more reasonable i.e. 50’s to 60’s max.

 

I have an EK custom water cooling system on the way, but I feel like I need something actively dropping temperature below ambient to get good results.

 

I watched the video on chilling threadripper 2, but the aquarium chiller is no longer for sale. Is there any other chiller under $300 that’s not garbage?

 

Thanks in Advance

IMO it would be cheaper in the long run to get a half decent AC system for the room, rather than trying to cool the CPU itself... just my opinion.

Subambient temperatures will cause condensation. Condensation will cause PC death. Get AC.

Just do what Jay did and as a bonus it will also cool you down (as long as you exhaust the hot air outside)

Update: It could cost a lot of money to get an AC that could dissipate heat outside of my room, so that is out of the option. The cheapest solution would be to get a chiller for the PC.

So for a chiller you can get Hailea chillers, for most people just going sub ambient the HC300 or HC500 would be enough.

 

However, in a hot humid attic room, going sub ambient is just asking for trouble, you WILL get condensation and it WILL eventually kill your system.

 

The advice about an AC is best. grab a small portable AC.

 

Beyond that ur looking at building either a dry gas case to prevent condensation and then chilling the loop using a chiller, or building a chill box where you chill the air inside as well as the loop itself, and use a desiccant to absorb as much moisture as possible, condensation forms on the coldest part which should be a radiator circulating air inside the box. Both require some DIY and have costs involved, and both require condensation protection being used on the components, such as dielectric grease, liquid electrical tape, neoprene, etc.

Condensation is a result of temperature and relative humidity. The goal is to have the chiller set to around 40°C, well above the dew point for the room. Condensation will not occur in the PC at 40°. I’ve done the calculations.

 

Portable ac units cost almost as much as chillers, but I’d be using more power over all running the AC vs the chiller.

 

What I need, and what I asked for, is a good deal for the chiller.

So ... the chiller ..of which i already recommend which ones to get ... where is it going to be located ? in the same room ?

Yes. Same room. Right beside the PC. At 50°C and 60% humidity, the dew point is a little over 40°, but I'm going to have a micro-controller on it to run it at least 5°C above the dew point at all times. Labview FTW.

I honestly don't know how well a chiller would even operate at such ambient temps, thats toasty to say the least. I'm surprised you can stand it ur self to be honest.

 

I dont know what ur situation is , but maybe you should consider having the chiller in another room that isnt so hot, and run tubing from it to the PC. That would get you away from the noise of the chiller and allow it to run more effectively. In regards to temps though, 40c liquid temps is still very warm, ur likely still going to be looking at high operating temps for the PC.

 

I'd suggest building a cheap cool box for your PC, running the chilled liquid through a rad inside the box and some fans circulating the air , reducing the box temps allowing u to go lower on the loop temps. Wouldn't cost much tbh, some wood and some foam for insulation to keep the cold air in.
