Default Re: MCW 452 chiller build

looping that beast must be mind boggling.

======
To check psu I would get a multimeter and check how many amps and what voltage you are getting at the pelt.

I would check water temps like brain suggested but I'm pretty sure what the main problem is.

The loop will have have Qt of 275-300 watts and not 400 watts. You're system at idle is running close to Qt and higher at load so you are getting bad results. Plus inefficiency. If you can't get the chiller to perform right I beat the two rads will be enough.


1) tubing size is too small. Bigger tubing size would improve performance alot. Doesn't help you have alphacool flow killers in sli config either and you need to insulate those puppies.

2) IF psu is underperforming. Getting meanwell psu will help a little if you can run at 13.5-14 V. Meanwell PSU SE-600-12 power supply on ebay is up for bid.
