Nice screenies fugger :D
:toast: VERY NICE INDEED!!!!! i agree with marci you should post a guide.:thumbsup:
no differance you will notice.there is no cooling differance in the 2.about 2 to 3c diff but the higher pressure off sets it so they are almost equal.if it was colder i surely would be using it...LOLQuote:

Cuz despite the wrong temps it's really important ( for me at least ) to know if the NL11F ( If I'm correct ) will sustain the "load" from the R507? :) :confused:
the 2 are the same price too.it is just a matter of choice and what you are used too.
That is freakin crazy Fugger. Great job man!
Hehe, very very nice! So what are ya cooling the vid card with? hmmm?Quote:

Ohh... i see.... thanx man, so the 404a is still the way to go :)Quote:

Fugger, the way you're going soon we'll be seeing 5GHs shots @2V m8 :D
The prommie compressor is designed for R134A. This means it can not only withstand the normal operating pressures of R134A, but also a certain amount of abnormal pressure. For example, if the condenser fan quits, the high side pressure will rise very quickly, and the valves must be able to take it.Quote:

When we change to a higher pressure refrigerant such as R404A or R507, it's normal operating pressures are within the (abnormal) limits of the compressor, and there should be no problem, although it will probably shorten the lifespan of the compressor.
But what if the condenser fan motor quits, when using the higher pressure refrigerants? Now we are talking real pressure.
Probably the compressor will kick off on overload. Also, there is an internal relief which will bypass pressure back to the low side, thus limiting high side pressure. Will this save the compressor from internal damage? Maybe, and maybe not.
That's why going to a higher pressure refrigerant voids the compressor warranty. When you switch refrigerants, you take your chances.
Well, we void the warranties on everything else ;) May as well go for the full monty. :toast:Quote:

i have tested this,in the beginning..as that is why i always wire the fan direct full speed.
i am sure no one else has good to the extensive testing i have,but thats just me i guess.i want to always know worst case.
i know for a fact the compressor will hit 400 psi on the high side and still climb.before i decided it was enough and connected the fan.it will blow the condensor easily i believe.but some will find out the hard way.
but yep these high pressure refrigerants can be dangerous
I wonder how much pressure the prommie condenser is rated at? Are there test pressures listed on the unit specs?
331 psi high 174 psi lowQuote:

Yep, sooner or later one is going to pop. To make the system safe, it should have a high pressure cutout switch, which shuts off the compressor at 300psi:

yep i have a bunch at work we use.easy to use just screw them down on the access firring and wire in a relay to the main compresor feed.i would proberly use a normally closed one set to 325 to 350psi.Quote:

but any any one would work just depending on how you wire it up.
BTW, that's a website worth browsing. Supco makes lots of interesting accessories for the refrigeration industry, including start kits, time delays, etc., etc., etc.
Of course, you could just use 2 fans on the condensor. Greatly reduces your chances of catastrophic failure if you got some redundancy there.
Are there any other situations that might cause serious problems w/ these refridgerants? Some risk I can deal with... stuff exploding in my bedroom? ...makes me nervous.
I did another obvious change last night. Instead of setting alarm @ -65c I moved it down to -30c so that the fans never slow down between -32c and -52c.
I had to stop early last night.
nice 1 m8, let us know if it blows up :P (lets hope not)
Which alarm exactly? Doesnt the one that causes your fans to run fullspeed also turn off the heater in the evap head? (soz, i'm not home now, dont have the docs handy).
S25 or S26, I dont have book handy atm
Lol with that 3DMark03 CPU score. Nice run and impressive for P4. But just yesterday i did exactly the same 977 points with FX-51 @ 2.4 on air:)
haven't uploaded it - just thought it is not interesting for anybody... LOL! And that was the world record :D
OK..guys..all this sounds very exiting. BUT one thing that crosses my mind.
When you´re doing the R404 modd...it´s said that you should extend the cap.tube with aprox. 1.5m.
Is this suitable for the R507 to...will it benefit from extending the cap.tube. ....or is a plain ref. exchange enough..??
Anyone with a good answer ..??
Seems like just a refrigerant swap works pretty good.
But I assume extending the cap tube will get you lower temps.
Although this might put extra load on the compresor, maybee bowman, Gary, captaincascade or one of the other experts can say for sure.
If you extended the cap tube to its "correct/optimal" length then might the conpressor be unable to start at all?
OMG Fugger thats awsome ! :toast:
So what is stable ?? atleast bench stable ! lol
