Regassing

For everyday use there's nothing wrong with r134, in a Mach2 it's better than any vapochill SE, PE or XE (not XE2).

Thats good enough to get the best from Northwood, XP, Sempron, Winchester (although with winchester @ 3ghz temps under load hover around zero which is not the best).

Newcastle core - needs r404/507 to maximise potential.

FX53/55/57 - R507

Clawhammer 4000 - r404 or r507

Dual Core - r507 (Intel Dual Core will probably need cascade :D )

So if you regas and want to run what you have at the best overclock and protect your investment for future upgrades the answer is r507 (still runs cooler and quieter than any Vapochill LS model).

So I would choose r507 (Mach fans set to 90% of full speed), but 404 is not a bad choice (fans can be left on normal 24/7) if you sleep in the same room as your PC and leave it on overnight.

Hope this helps, good luck in your choice my friend.
 
Well.... I was hoping to move to a dual-core so looks like R507 is the way... sooner or later.

What are the differences in the gases? Why would R507 have a higher pressure? Is it at a higher pressure from the time its put into the system, or does it expand more with heat? (thus making it the better cooler if it moves away from the CPU faster)

Why is hovering around zero degrees bad under load? Compared to my max load temp of +50... zero is a LOT better!

if I have a re-gas to R507, will that mean that the simple act of turning my computer on at all becomes A Big Deal for the motor? Or does it just not like restarts as in.. computer crash and restart. What happens to the motor, evaporator and condenser when a start or restart happens.... I want to understand this gear i`ve bought.. normally I learn from mistakes (both my own and other ppls) but... theres too much to risk here to learn that way, methinks

LOL... lots of questions!

Thanks for the help with this everyone :)

hovering around zero, then going real cold (during idle) then hovering again at zero present more of an opportunity for thermal expansion/contraction which can lead to condensation and other complications of the components contained within the kit.

If it's not -4 or lower under load then it's an issue (24/7 not intermittent benching).

In summary lower than -4 is good 24/7, between -4 and plus 2 is good for benching (maximum overclock minimum time).

Or if you are watercooling (or using a water chiller) then over +18 degrees is desirable (moves out of the condensation temp range).

Reference the gases - it's all about boiling points and stuff like that, it gets real technical if you really want to know - fatty may be in a better position to assist with tech details. The caveman approach to the gases is like this cold=r134 colder=r404, coldest=r507, extreme = r1024 (i think), bonkers = LN2/DRY ICE.

The extra pressure is caused by the expansion of each gas - seems how the compressors are straight from domestic fridges, the average life is around 10years - a regas probably drops that to 5 yrs, of course in 5 yrs who knows what we'll be running?? The only thing to last me that long has been my desk LOL.

Repairs and replacements for this kit are available from this site.

At least thats my opinion..... for what it's worth.
 
Your opinion is worthwhile :) You have experience- you could tell me that R507 smells of strawberries-i`d have to believe you ;)

Anyway... just had a quick look at the Asetek forums and theres a few comments on a cascade thread (with heavy name-dropping of Mr Gray Mole) that Vapochill PE`s dont like R404, let alone R507.

That could be the end of that one...

Have posted to find out what the differences are between the components used in the PE and the EE- if I REALLY want a re-gas, I could always try changing some components.. and that comes back to the "expensive mistakes" comment..

Sometimes I get the feeling I shouldve stuck with watercooling... :D

Lol.... just read that post as well- thanks for replying :) Sorry if i`m making people reply to all my dumb questions twice... was tryin to do that "initiative" thing where I spread my lack of knowledge around several places to get as much info as possible :)

But dont release any into the air just to smell it ;) , AFAIK it is illegal to release such gases into the air intentionally isnt it, and when regassing you must reclaim all the of old gas (or as much as possible) dont you?

Im happy to answer any questions K404, no one is forcing me to post on any forum :), it is good to cross post in cases like this, as most regas knowledge on here AFAIK is with Mach units, not PE's, so the vapochill forums can provide you with unit specific knowledge, and there are many experienced and helpful members here to tell you what you can gain, what the costs are etc.

Can i please ask what releasing excess gas intot the enviroment does ? Does it harm humans? Or simply remove more of the ozone layer ?
 
It is illeagle to vent gas and if you are caught doing it you could be liable for a £500,000 fine and or imprisonment so not only does it harm the ozone but it will harm you too....

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.

Click to expand...

Hey again! If I dont re-gas, and leave the vapo charged with R134, can I restart as normal? (ie no hour-long delay) Software installes and failed OC`s are gonna create re-starts, and a Windows re-install would be something else totally- an hour between restarts is... no use to me :) That kind of convenience is something I think i`d choose over those last few MHz of an OC

When i say a restart, i mean restart the cooling system, so if you just reboot the motherboard and system then the cooling system will just run all the time so there is no need to wait around.

It is only once you turn the system off you wont be able to turn it on again that quickly (how quickly can depend on the gas charge you use)

If you leave the r134a in there the compressor will have no problem starting, r134a is what the compressor was actually made to use, so it should always start.

That fits with what I was thinking about the state of the condenser and CPU when a restart occurs:) (wasnt sure about the vapo restarting tho)

:-D

Thanks
