CES 2015: Captherm Shows Off MP-1240 Multi-Phase CPU Cooler

Though most of the companies on the show floor aren’t ones we post about often, I was able to catch up with the kind folks of Captherm Systems out there. We heard about this technology briefly last year when they announced the MP-1120, but were not able to see it in action until now. It’s quite impressive actually. Captherm’s products are the only consumer cooling solutions on the market to use a multiphase design, which takes advantage of the change from liquid to vapor. What you can’t see in the photo below, is that the refrigerant is actually bubbling, so you can see the cooling power in action.

Captherm’s latest cooler, the MP-1240 (not pictured), took home a CES 2015 Innovation Award. The 1240 uses the same technology as it’s predecessor, but utilizes a larger heat exchanger with up to four fans, increasing performance. The MP-1240 features 100% metal construction and hermetic joints. Captherm feels this could really be a game changer, so we are pretty eager to see what the performance is when it hits the market.

This cooler will not come cheap, likely in the $250 range, which can get you a fairly nice custom water cooling loop, but not the same space saving advantages of the MP-1240. When asked about the performance relative to a custom loop, Captherm’s tech lead said that it all depends on the size of the radiator in your loop. He does however expect it to beset all AIO coolers in the market by a longshot and challenge just about any custom loop. One could likely spend the same amount of money on a custom loop to achieve better performance, but that also comes with the recurring cost and time commitment of maintaining the setup. Caprtherm has essentially solved that problem with a closed loop system that requires no maintenance of any kind.

A cautionary note from Legit Reviews here.

CapTherm said that the MP-1120 would be available in late Q1 or early Q1 2014, but the cooler was never released. When we saw that they were going to be at CES 2015 we were a bit shocked as they had a new cooler called the MP-1240 they would be showing off. The MP-1240 is basically the same thing as the MP-1120 but with improved performance through a larger heat exchanger with the ability to run a total of up to four fans offering leading edge thermal performance. From what we gather the CapTherm MP-1120 is rated to handle up to 275 Watts and the MP-1240 can handle up to 325 Watts. The CapTherms MP-1240 might not be able to fit in many cases due to the position of the fixed heat exchanger. . . .
For the second year in a row we got to see the CapTherm MP-1120 running. This year it was on an ASUS Z97 motherboard. It was great to see the CPU cooler in action, but again there were no temperature results or benchmarks to be seen. The CapTherm MP-1120 has been demonstrated for more than a year now, so something seems off to us. If the CapTherm MP-1120 is that great why aren’t numbers being shown? Legit Reviews is from the Show-Me State and we feel it is time to see some numbers. CapTherm Systems did tell us that there was an obvious flaw discovered on the MP-1240 and went on to say that anyone would have seen the flaw. Not a good sign for a product that has been in the development phase for nine years now. . . .
Our skepticism of Captherm Systems is also slowing increasing as we’ve seen them at two Consumer Electronics Shows now and we walked away both years without firm details on pricing, performance, availability or anything like that. Some sites are reporting that there is a $249 price tag on this cooler, which is a bit expensive for a CPU Cooler unless the performance is phenomenal. Even if the CapTherm Systems MP-1120 and MP-1240 Multiphase CPU Coolers can perform 2-3C better than a traditional water cooler would they be worth paying 2-3 times more for one? After looking around we found this document that claims CapTherm has come up with We are hoping that CapTherm will have review samples ready soon as we are dying to see how these perform and would love to see some hard numbers! After working on something for nine years we think it is time to see some results!
