One part of the industry that requires millimeter precision is building systems for small form factor designs – being able to take advantage of every small bit of volume inside a chassis but also maximize performance yet minimize noise is a critical element to the success of these systems. ID-Cooling has thrown another hat into the ring when it comes to cooling the processor, something that can be a tough job in such an enclosed space. The new IS-47K is designed with a maximum height of 47mm, and is apparently rated for CPUs up to 130 W.

Featuring six copper heatpipes and a 92mm PWM fan measuring 15mm thick, the IS-47K situates the fan in between the copper contact plate of the cooler and the heatsink, pushing air up through the aluminium fins, from CPU to outside. The whole element is nickel plated, along with a ‘metal frosted’ frame to keep the dimensions nice and snug. Judging by the renders, this cooler is designed to sit just on top of the rear IO, with a stepped type of cooling to facilitate rear connectors that come back a fair way into the socket area.

It should be noted that while this CPU is rated to support a TDP of 130 W, some processors during turbo modes will surpass that 130 W limit. Users will have to adjust their BIOSes accordingly.

The IS-47K offers brackets for all Intel LGA115x/1200 sockets, as well as AMD AM4. It comes bundled with ID-Cooling’s own TG25 thermal grease, rated at 10.5 W/mK. ID-Cooling claims full memory compatibility with all mini-ITX motherboards, as it doesn’t go over the top of any memory modules. This means that the double-height G.Skill modules, enabling double-density on certain motherboards, should be suitable.

The IS-47K will be sold for $45 at the end of June.

    Getting at the mounting screws could be an issue; don't see how that can work well.

    One of the other images on the ID-cooling page implies the screws are installed from the back side of the motherboard; so instead of screwing into the mobos backplate from above you'd screw into the retention bracket from below. Having to remove the factory bracket makes installation a bit more complex; but it's something waterblocks have required for many years now so it's hardly an alien approach. And it's not like every step of a very compact mITX build isn't an exercise in contortion already. :)

    That is already in the market designed by Dan from A4-sfx called Alpenfoehn® Black Ridge. I bought it like last year.

    I think the black one is wider, touching ram slots maybe. Do they ship with angled screwdriver?
    I don't think I would have anything that would be able to screw it in.

    It's like what Dan says. You just have to turn it over and get to screwing from the backside. That's how most of you guys should do it anyway even if it is a pain in the butt.

    I'll have to look inside my case for clearances but this would be nice for getting an AMD 3900 in my ITX case.

    130W TDP is pretty good - can't wait to see the actual tests on it. The well-regarded Alpenfohn Black Ridge is only rated for 95W TDP, so it will be interesting if this one can actually dissipate more than the Alpenfohn.

    That 47mm height is also the height of the Alpenfohn.

    Also, they could have dropped the "metal-frosted frame" and just supplied better mounting hardware, if/when you decide to replace the 92mm fan with a quieter/higher-performing one. Some cheap wire-frame clip-ons would have been better than just screwing right into the frame. It could possibly make it easier to get a 120mm fan underneath instead of the 92mm, if your surrounding h/w permits.

    You need to take the 130W TDP cooling capability with a bunch of salt (not even a pinch). If you look at the current product stack from ID Cooling, especially with the low profile coolers, I feel the cooling capability is somewhat overstated. I was using a ID Cooling IS-50 that was rated for 100W TDP cooling capability, and it actually performed very badly. Considering this is almost a replica of the Alpenfohn Black RIdge, I am more incline to believe the conservative 95W cooling capability than what ID Cooling is quoting with this cooler.

    That is honestly all I am hoping for (95W). I have an Alpenfohn Black RIdge (and Asetek 645LT and a Noctua NH-L9a... I have a habit) in my Dan A4 (v4) and I currently am using VLP RAM so I can fit the 120mm fan in there. If I could have the same/similar cooling with full height RAM I would be very happy!
