Very clean build, looks fantastic and seems to perform very nicely! I am beyond envious that you can get ethylene, I've been wanting that for the last 20 years or so.

That should work just fine, however the schrader valve will be a big restriction even without the core, and so will the small refrigeration hose. If you are doing it that way just to have a flexible...
Nice job man! Brings back memories of the good old days.
Wait, how do you know your exact CPU temperature? Evap temp isn't meaningful, actual CPU core temps are.
Yeah precisely, fan controllers are essential for big ambient temperature swings. That is why most RTU's (roof top units) have fan controllers and/or head master valves for winter/summer operation....
His measurement is only evap temp not CPU temp so you're right, the cpu is probably much higher depending on the evap design. Most CPU evaps you buy from guys that machine them have a lot of mass but...
A larger efficient condenser can increase efficiency when the expansion device is set correctly for it, assuming the smaller condenser was increasing high side and getting warm. Less strain on the...
I told him to get rid of that sight glass and receiver awhile ago and I believe he did and it started working much better. Also I am quite sure these 300w heatloads are not right. Just look up what...
Yeah -55c and even lower is very possible without a load Buckeye. His post right above yours said -40c which I am assuming is under a load. That seems about right and it isn't actual CPU temp, there...
You need to add it under a load slowly to see if it helps. Add a little under a load then let it run that way for a few minutes and see if temps fall. If not then the cap tube is too restrictive.
...
Yeah it very well could be undercharged that's why I said start by adding some refrigerant and see if that helps since it's easy to do. Do that with full airflow though. If it doesn't help then you...
First I would try adding some more refrigerant since that is easy to do, but my bet is on the cap tube being a bit too restrictive since the high side pressure is lower now that it is cooler and...
Nice, looks like it's working very well.
Nice, it looks good!
Oh wow nice, you have quite a collection! I was just joking about sending me hardware though haha
You have a lot of CPU's to test, might as well send me some hardware to test on my autocascade! :p:
Yeah that is working great, very nice! Oh and you're right, it should do even better when your ambient temps are cooler.
Ah ok, not sure what that looks like inside. I was just curious. I have an evap that was on my old autocascade made by teyber I believe. It's a stepper kind of thing. Tons of mass and super...
Awesome, glad it helped! For fine tuning to get better temps it would be good to get some evap in and out temps with a load so we can see if your charge and cap tube is right. Seems pretty sweet so...
Yes, you always want the liquid line exiting the condenser to be straight as possible. Liquid doesn't climb up very well, so you end up having to overcharge it to get enough liquid at your drier...
If it were overcharged your compressor would be icing up and you would be getting liquid returning to the compressor. You can try removing a little gas to fine tune the charge under a load since cap...
Yeah that static pressure is fine. R-404a is a fairly high pressure gas so it's normal to have a higher static pressure than something like R22 or R290 for example. If you were using something like...
What are the temperatures and pressures under load? If possiblewe need the following temperatures: evap, suction line 6" before compressor. liquid line temp and condenser air in/out. I am not sure if...
I'm assuming this is still using R-404a? If so then all you do is use the P/T chart for R-404a to determine static pressure at a given temperature. For r-404a a static pressure of 175psi indicates...
Same here kayl, that's why I say start long then cut down. Beats cutting too short then having nothing to work with afterwards. Nice to see you around again! Seeing your -100C Club Member name makes...
