Swiftech MCW7000-T for Corei7 announced

[zipdogso]

It will have to be well over 250w. I have a 226 pelt hooked up to a 320-15 Meanwell. Just for grins I put in on my i7 920 overclocked to 4.0ghz under a really good water cooling system. As I was told to expect it promptly was overwhelmed by the heat of the 920. I had my alarms set at 75c and they went off at about 2 minutes and temps were still climbing rapidly. Without TEC the same water cooling holds temps at 4.0 to about 70c fully stressed.
If Gabe can come up with something at ~400 watts I will go for it. Much less and I don't think it will be worth it.

The problem is Gabe said he was looking for efficiency at 12v...

Well half the world thinks the efficiency point of a TEC is 75% max power which might indicate he is planning to use a 15.6v TEC. A 15.6v TEC is a 127 couple unit and there are some hefty ones about especially as it was hinted it was a custom unit. To be bigger than 275w at 75% power it will have to be at least 350w + Qcmax so it will be at the limits of 62mm 127 couple design I believe. You certainly wont get the 400w your looking for....well not in my estimation anyway - that's why I thought his original posting was very hard to believe. I think it was a brave thing to do to make an announcement like that when at that point he didn't even have a TEC to test let alone consider how he was going to power it- -I just hope that hasty decision does not impinge on his business too much !

He could be using a TEC with a higher couple number especially as it was hinted it was custom but the undervolting efficiency point is the COP efficiency point of around 30% max power but to get 275w at this point is just ridiculous. Not least the average Joe bloggs wil have difficulty getting the 20ºC delta needed to reach that efficiency anyway.

So he could use a TEC with a large couple number and carefully choose the undervolting to 12v but he will be a way off the so called "max efficiency" he was referring to. Besides I wouldn't to run a 400w TEC at a COP of 0.5 - 0.75 (which is what it will be in this scenario.) for any length of time not with the massive cooling system that be required with it.

So what was Gabe talking about ?

It really will be a magic TEC.....

To be honest I think single TEC direct die cooling has nearly had it's day due to todays high TDP's a multi-TEC cooler is a much better proposition - Coolit's offerings are about at their peak due to their use of molex connectors for power so all that remains really is self-builds - with too few people around who know enough about TEC's to implement it effectively.
