Nah as thats pretty standard.
Is it standard for when these compressors are not used for cooling computers? Eg in a fridge
Many times so that if you look at condensing units, they are either fan cooled and/or cooled by the suction cooling provided by the refrigerant.
Ah sorry, i thought that with fridges etc only the condenser was cooled not the actual compressor.
I had actually thought about extra cooling for the compressor shell a few days ago after noticing how hot the compressor in my overloaded stock LS gets.
Nothing crazy, maybe just some fins strapped around the shell to give some heat dissipation area to the shell itself with a hose clamp type arrangement. I wonder if the hvac folks have such an accessory available?
I can't say for 100% that there is not a device to suit your needs, but I suspect it's going to be extremely unlikely that you find something commercially.Quote:

Our compressors rely on cold "GAS" returning to the compressor to help cool it down. What happens if your unit is a little under charged? One symptom is the compressor will get very hot.Quote:

I have been using 0.031 on all units and they are more than capable of cooling high loads.Quote:

NF9FX simply is not good enough, Over here in Europe/UK NL11f just about cuts it.
I dont think current evaporators can handle much more than 250w without problems, especially stepper/spirals.
As technology plays out, compressors are getting more effiecient. Some companies have very efficient compressor ranges that have higher displacement and lower power consumption than the popular Danfoss models.
I think people are stuck on Danfoss compressors for some reason thinking its the best out there. In my experience its not.
That works, or switch to a longer length like .036, which is equivalent to half its length in .031. 6ft of .031 becomes 12ft of .036
I think you've got it backwards ;) But even if the numbers were switched, they don't actually calculate to be anywhere near equal :confused:Quote:

Jesus...I'm stupid...I read your post wrong - sorry....it's WAAAY too early for me :coffee:Quote:

i don't know what to do know should i buy an mach2gt yes ore no?
Its not a linear line from some of what I've seen. 6 feet would be good for a quad core with heavy overclock, change it over to .036 to get enough for proper subcooling and the length also helps with the pressure drop. I'm going to test this length, but I may start with 14 feet and work down (7 feet of .031)
I don't mean to speak for him, I don't think NoL has a quad, but he is working with me on a custom build for my QX6700, using a SC12MLX, with .036 cap and large condensor. Shooting for tuning at 300w with his load tester, which will provide him with a 300w power load to simulate the quad at very high OC. It is a work in progress.Quote:

The concensus is NO, unless you plan to get it modded. Please read the entire thread.
Have to remember there soddem, clamp meters are not accurate enough to measure current. even a fluke. For an accurate reading you need to wire the ammeter in series with the load. Most clamp meters have a guaranteed accuracy of +/- 30%
Yeah I think the idea of myself using this size capillary, which should indeed work well, and then tune the unit, AND THEN record the evap temperature at every 5watt increment, then Harv can tell us what the evaporator temperature is and I can say what the wattage is.
yes thats a good idea there Nol
We need to collate as much data as we can about these warm processors. :)
Keepa is getting close to getting all the bits he needs for the beast he his building. I think he finally decided on a QX6700. I'll share his results when they come in. That's going under the 500w chiller i built btw. :)
Ah k, only waiting on the .036 to build Harv's unit and then we'll have our load number in a few weeks. Until then I think we can find another method maybe?
Are you sure that is with using the clamp? not wiring the ammeter in series?Quote:

even so. I wouldn't be asking for readings from noobs with $10 clamp meters. That will not give you the stats you want. +/- 30% is a far to greatly varying reading done by cheap meters.
