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.

    I bought my C7 for like $30 a couple of years back. They are like $90 in NA the last time I checked. Therefore, I'm open to alternatives. Reply

    Yeah, looking at the "amount of metal" it lacks the actual "heat sink" capability a good chunk of copper comes with. also the radiation area looks small for 125W.

    Until someone really independant tested that with a 125W TDP CPU and not thermal throttling I would be VERY sceptical of the advertised capabilities.

    My guess is they've slapped a faster-spinning fan than the Alpenfoehn has onto the design and called it a day. Wouldn't be too surprised if they didn't even do that, though. Reply

    I feel this may be a good alternative to Alpenfohn Black Ridge if the price and availability is good. Currently, there are very limited channels to get the Black Ridge. Reply

    Would be fine for 125w or a bit more if a case fan directly on top of it is pulling hot air out of the case, i.e. Silverstone RVZ/FTZ series. Reply

    This looks like a compatibility nightmare with current itx boards with hunks of aluminium for "heatsinks" Reply

    Im more concerned about cables and stuff. SATA cables, power cables, USB cables.
    Some cases are so small (Pico PSUs) that you might not be able to fit in all the cables anymore at all, because theres simply no space to put them anywhere at the sides.
    And if you want to disconnect those cables or add now ones, you would most likely to always get the heatsink off, which is a lot of work considering its screwed on from the back of the mainboard.
