Mach Vs Vapochill for temperatures

[K404]

My old VapoPE held my CPU at around -5 to -10 at load (Winchester at around 1.65V), and from what I think i`m seeing, the M2 GT "only" manages the same kind of temperatures... what kind of load temperatures (CPU) do you all get?

Thanks,

I thought that the MACHII GT is significantly better than the VC?

Thats what I thought Indeed, i`ve just sold my PE and bought an M2 GT based on that thought Theres been a couple threads recently where load temps have been mentioned, and they werent THAT low... Maybe I`ve been interpreting them wrong

Isnt it something to do with the load applied - mach2 GT's are 'tuned' for 210w @ a given temp vapo LS are tuned to 240w (newer ones 210w), winnies dont pump out as much heat and therefore the temps although sub zero are not maxxed out or could be classed as innefficient at those temps?

They can be tuned for better temps at a given load (probs needs setting to 180w) or you but a new cpu in confidence knowing u got extra cooling capacity.

Good point. It would be good if the units had some way of letting Average Joe tune for best performance depending on whatever chip we`re using..maybe some way of moving some gas to a second chamber where it wont be used? Or Something...

Example...From the Vapochill graphs, which are accurate, my Winchester was dissipating between 55 and 70W at 2800MHz-ish, depending on the ambient. If a Mach is tuned to temperature at 210W...Theres a MASSIVE difference and potential loss in performance there.. I sense that when I get my Mach up, my chip will be very very cold, and it wont even be as cold as it could be. Time to stockpile armourflex and Di-elec, methinks

That sounds like an excellent idea, if only one could be made... A job for skinny me thinks

LOL...most of my ideas sound good, but fall apart like epileptic lepers (sorry) once scrutinised by ppl who know what they`re talking about

Ok a standard GT will not hold 210W of heatload FACT the ones I tune do as I tune them for that my r507 chilly1 unit in bios reads around -19 with 1.6v running through the core and clocked at 3400 under 100% load it will vary 2 to 4 degrees depending on the ambiant however I cant seem to find a program that isn't buggy that will read the bios temps even mbm5 wont properly

funny, i always thaught machs were waay better....

A GT must be getting the chip colder, it's using r404a whereas the PE is using r134a, so i think the problem probably lies with the sensor reading the temp.

If you got a thermocouple in there and read the real temp you would probably find the GT was way colder.

The tweaking idea would be awesome Kenny, but as always not very practical, the only way you can really do it is if you build the units specifically for each chip you have and the regas for chip you buy. 200W is generally enough to max out most chips whilst not losing too much in the range in between.

LMAO, eww.

I agree, to really get it right, the unit would have to be tuned properly for whatever processor was being used, which takes an experienced HVAC, most of the time. I`m expecting the temperatures to be much better with a Mach, i`m hoping to find a way of getting a physical tyemp probe onto the CPU surface to be sure, but without breaking the condensation seal...at the moment i`m thinking a neoprene stack should do it.

If I keep coming up with enough ideas, I`ll hit on a practical one eventually
