Not quite! r404a is used in the GT. And we know it invalidates your warranty but then for better performance it's kinda worth it.
I would be interested. How much you gonna be chargin for the service mate?

What warranty? Any with nVentiv are U/S, only Phil's is OK afaikname='HARRY' said:

I might be interested, how much better is 507 than 404, what cooling performance increase could i expect ?

Well That seems great and a reasonable price too.
If you are worried about the circuit board you COULD get us to remove it before sending the unit to you, as it is the most precious and easily damagable thing in the unit, which isn't replaceable. It's just a matter of removing a few cables and unscrewing it surely, then you wouldn't be liable for breaking it. Of course that asumes you don't test the unit.

That sounds like a mighty fine idea too but I know some people wont be interested in removing their own cct boards but they may well have too as I said I will have one unit as a standby unit I cand use the cct board out of it for testing etc judging by the response it looks like I will move ahead with my plans as I said it wont kick off till december as I will mod mine up when I get back from holidays and share the results

Fatty - I bow down with respect for you trying to see what you can do in this area.
-75 degrees is a true overclockers dream.
Somethings you may already know but I'll post anyway:
If you regas to r507, others recommend that you always run in turbo mode (prevent overheating and bowing of the Mach framework).
Oil change is recommended to one more suitable for the gas used.
Always run the system under some load to prevent ice build up (internally and extrenally) on the cooling head.
Things I'd like to know about is:
How much extra noise is generated (compressor, fan etc...)
Best temps achieved (head and typical overclocked CPU under load.
I am in the camp that would prefer not to remove anything before I send to you for shipping - it's as much to protect you as it would be to protect us, nobody can use the excuse 'it was working when I sent it!!' and you get to test with the components we will be using.
The only warranty I would expect is one that says it reached a lower temperature and it does not leak. Anyone with an Nventiv unit lost their warratny when they went bust - unless Phil or someone offered an incentive to purchase. But modding a Mach is like modding a MOBO - IT VOIDS YOUR WARRANTY
Price should be around £100 to include return carriage.
Good luck with your project my friend, I hope it works and feel sure people will take you up on your offer if you are successful (My friend and I may be one of them).

Cheers for the post but one of the main areas I looked into was oil and r507 does use the same oil it is ester oil (think thats how you spell it) but i did a bit of research
And I do like the warranty idea

I will keep everyone posted on this and will make a start on my unit in december

You'll find it difficuly to regas a unit without a controller board as then you have no way to monitor evaporating temps whilst the unit is under load, unless you build a fixed wattage load tester rather than load testing on a CPU.
r507 uses the same oil as 134a and 404a. No change is required unless that oil has been exposed to the air for an extended period of time... in which case an oil change and drier change is required to be on the safe side. ALWAYS change the drier. If you don't get all the moisture out then it can be a life saver, and if you don't change it and the unit develops a problem then you don't have the fallback...
r507 has no tangible benefits over 404a. There is very little point regassing a MachII GT over to 507. You'll get about 2 degs colder. To make an effective change on achievable CPU Speed the temps must be shifted by at least 15 deg on a regas or it's just not worth doing. Only time to regas a MachII Gt to 507 is if it's leaked all it's 404... but even then you're better off giving it 404 unless a full triple evac and purge has been done on the unit.
Extra noise generated? Minimal. Run your current unit with it's fans on turbo. That's the amount of noise a regassed unit will make.
Lifespan decrease: about 1.5 years off the units total (estimated) 15yr lifespan on it's stock refrigerant charge.

Cheers Marci where did you get your driers from?? Just out of curiosity I think I saw a pic of one on your thread anyroad I think I will be triple vaccing all my units using ofn so I dont think there will be any moisture what so ever and if I am doing sealed units there will be little exposure to atmosphere except when the shraider goes on but I will look into the driers aswell
What sort of heatload is typically catered for after a re gas? IIRC (from Marci's posts on his forum and others), you have to spend a while tuning the unit to the required heatload to get optimal performance?
You know I'd be in there quick as a shot Fatty, especially after virtually barbecuing my Prescott a couple of weeks ago (my own fault for trying ridiculous frequencies and getting the Prommi into positive temps)
Good luck matey
