Regassing

What benefits are there in regassing phase systems to...404, 507 etc... Do they help get colder temperatures?

Thanks,

Kenny :)
 
yes. thats why the GT has better performance than the ST. but my ST (using r134a) is getting the Evap to -60 at the moment on a default speed 3000+ venice core. ok so its not a fast 64bit chip but its ok for me at the moment!
 
If i`m gonna get a regas...it really should be 404, shouldnt it :-p I didnt know bout 404 gas when I picked "404" as my gaming name :)
 
Why should it be 404 and not 507? If you're going for a regas perhaps buy a new block as well while you're at it?
 
R507 is the better option it handles heat better I have a mach2 gt which is 404 if I stick my test heatload onto the gt it will not hold the temperatures at all, even if i leave the fans on low with my fx overclocked the system shuts down and says too hot :)
 
It depends on what cpu you are runing. If you are runing fx55, they kick out a lot of heat and would benefit from the 507. I have just had mine done and under full overclock the temps idle around -12 as opposed to 0 on 404. Best thing to do is run super pie and have something like speedfan running in the background to see what sort of temps you are able to run. Although not exact they will give you a good idea. With the introduction of the venice and the san diego core, which run cooler, it may not be such an issue.Me pesonally i think cooler is always better.Hope this helps.

507 has a better performance over 404 - phil recommended i changed to 507 if i was going to re-gas.

Lol, i knew Mach LCD's were inaccurate but that is just taking the Gypsy's.

EDIT - and guys dont forget the drawbacks of regassing, often including having to run the fans faster, compressor life shortened, increased risk of condensation.
 
Well.... cooler temps mean higher overclocks? Thats why we`ve all gone/ are going sub-zero in the first place...

Was joking about 404 coz of my username :-p compared to R104 (i`m guessing whats what this vapo will have) would either 404 or 507 show a good increase in performance?

What kind of reduction in life does 507 have on the compressor?

Thanks,

Kenny

i dont have an LCD display. mine is all accessed thru the usb

Ah yes, i meant just the prommy software measurements (which determines what is on the LCD if you have one doesnt it?). What vapochill are you talking about K404?

The gasses for vapochills and prommys are:

SE/PE/Mach I/MachII ST = r134a

XE/ Mach II GT = r404a

XEII/LS = r507a

I dont know how much of a life reduction a regas will have, but im sure someone with regas experience like phil could give you an estimate.

I got a PE so R134... I was close :)

Thing is tho, I bought this vapo off Morgan at coolercases... seeing as it was his own gear (I think), somehow I wouldnt be surprised it has been modded... Will find out tom on the label :)

If a regas would that bad an effect on component life, I doubt many people would have it done, or offer to do it.

No one can give you a real life estimate if you run the fans at 1900 rpm or above with an r507 regass you will have no problems

No one can give you a real life estimate on how long a stock compressor will last yes 5 yrs is a good guess but it could last longer also the gt is not supposed to have 404 in it as the compressor is still only rated for 134a
 
As for the -60 degrees, its probably a calibration issue with the sensor - better to check temps in the BIOS or with speedfan or similar in windows.

I would doubt that a 3000 will strain your r134 filled unit for now and although a regas would help it run cooler it's probable that your max overclock will not improve.

An upgrade to anything higher than winchester 3500 I would recommend a re-gas to R507, R404 is good, r507 is best and they both cost the same to do.

But also consider that an r507 regas means fans on 90% to turbo 24/7 a r404 regas means you would be able to run normal fan speeds.

I am I the same camp as scorchio - cooler is better and with a mach2 avoiding condensation is easy, as long as you take your time when installing.
 
1900RPM... I was hoping to replace the fans for 12`s so is there a minimum recommended airflow needed?

Will have a look at my compressor specs and see if it looks like it`ll handle 507- good point there fatty :)

Kenny
 
Hey Mav... this thread is moving fast!... Do you suggest the 507 for a 3500 and above due to the maximum likely clock speed possible? To me, a 3200 and a 3500 are not really different do you think that to have a 3500 with R134 is selling the overclock potential short?

Kenny
 
I think the best person to ask about that will be fatty as he is the real expert on regassing and modding i'm sure he wil be able to help.

Colder is always better regardless my fx under a mach2 will do 3.2-3.3 under a cascade it may do 3.4-3.5 who knows some times its just the luck of the draw with overclocking
 
If you are going to regas your PE K404 then i seem to remember that a blend of gases is the way to go.

The PE, owing to its larger volume than the XE (BD50F rather than BD35F) can get hot start problems where the pressure is too much for the motor to cope with, meaning you will have to leave the unit for a while between restarts.

Also for a regassed PE i would get a seperate TEC PSU which you can get a nice strong, high 12V line, as this really helps with the increased work the motor has to do with the increased pressure. If you regas your PE i would recommend leaving it on mostly, or at least avoiding as many restarts as you can, especially the hot ones at they will put a high level of strain on the motor, causing it to wear out faster.
