Not to mention, figured it would cool down my case at least, I understand there is still an amount of heat released with the water cooling, but I would think it would be less than just air cooled case. Told ya I was a noob
personally i still see no need to run a cpu at any less then 4ghz. believe it or not your cpu is a very large bottle neck in multi gpu performance. 4ghz+ rely removes allot of the bottle neck. even in the most expensive state the price of electricity is around $0.135 per kw meaning if you where to run a phase unit using 500w/h it would cost you $48.6 a month running it 24/7. $24.30 for 12 hours a day. kind of spendy I know but is a extra 50%+ justify the cost?

believe it or not a larger powered water cooling system (8x 86cfm panaflo's and a d5) would only cost you about $4.86 a month, and would still provide a nice overclock and stability. phase isn't for everyone, and personally for a folding@home machine a phase unit would probably double your electric bill with ease, i don’t think the price: performance ratio rely justifies the performance gain, i think your better off with a high end water cooling system in your case.

Most likely though your phase unit will be in the 200 to 300W range. So a good bit less then that 500W/H actually. Half really.

Sorry, just being devils advocate.

thanks guys, I think I'm just gonna find a really good water cooling. I'm REALLY not interested in overclocking my chip to the hilt. I just didn't know what the performance difference between the two would be. I'm all for the lower electric bill, considering we pay like 18 or 19cents kw hr, and my bill is high enough! lol

thanks for your help.

I have been running SS phase units for close to 3 years now and have noticed no measurable increase in my power usage.

Prices vary but in general a SS (SS = Single Stage Phase unit) unit without a case can be had for around 350.000 and with a case for 500.00


General Specs for a decent unit: Danfoss nf11fx (powerfull but quiet), r507, 18 inch suction line, Chilly1 Spiral evap, 8 feet .31 cap, custom condenser, panflo intake/exhaust, no controller (rocker switch) and temp display.

Insulation can be found cheaply at Under The Ice site...

Strengths:
Maximum CPU overclocking
Reduced thermal degradation
Easy to setup

Weakness:
In general single cooling unit (Chiller if you want a cooled loop for NB/ GPU and CPU)
Loud (can be mitigated with sound dampening materials but unit should be tuned before adding)
Need to be careful to turn on SS unit (assuming no controller) and let CPU cool before turning on PC.


Just my 2 cents but I prefer a hybrid approach of SS cooled CPU and WC loop for NB and GPU.
Specs vary
