years down the line who were still in diapers when you started building computers but not thermal take no thermaltake took a metal heatsink okay i'm with you so far slapped a metal fan onto it because yolo in an attempt to cool down a modern CPU in one of the smallest form factor coolers that i've ever seen but does it work so if you were just here to find out if a metal fan would work then you'll be sorely disappointed because i'm also going to bore you with some science and history the sandia cooler concept with its metal spinning top and static metal base first showed up on the scene in 2012

then there was no news until cooler master showed up at ces 2015 with a couple kind of ugly prototypes that featured grooves between the spinning top and the base presumably to improve heat transfer

bunch of other small form factor coolers from reputable brands and a stock Intel heatsink since if it doesn't offer a compelling improvement over that you're clearly better off saving your money we used an ASUS z170i pro gaming motherboard thanks bros and a core i7 6700k with an nzxt grid 2.0 for fan control for each test we used a p sized amount of ic diamond thermal compound and we analyzed the results two different ways first we looked at what we could expect from each cooler out of the box using the silent mode curve in nzxt's cam software the engine 27 was the worst performing cooler in this test at about 10 degrees higher than the nearest aftermarket competitor under load and all of this while managing to be louder than the Intel box cooler as measured by our extech 407 750

than the nearest competitor from Noctua and less than half the height of the top performing ar-06 from silverstone the engine 27 is compatible with any case that's wide enough to fit a memory stick so with form factor as a consideration i'll be giving a few awards here today the ar06 gets my big and beautiful award for being the best performer if a little top heavy the Noctua nhl9i takes home the middle child award for being so ugly only its own mother could love it but otherwise a solid compact choice and the thermaltake engine 27 gets my better than nothing award for working better than i expected given its size making it a great option if you don't have anything else that will fit so congrats to the winners thanks for watching and good night and i've got another award this time for
