ID-Cooling Aims Low: 47mm Low-Profile CPU Cooler with 130W TDP

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.

Woot! Another option for DAN A4 owners.Reflex - Monday, June 8, 2020 - link
That was my first thought.FreckledTrout - Monday, June 8, 2020 - link
This is when max TDP's under normal operation would be useffull for desktop chips but I digress.Is it safe to assume this would be a competitor to the Noctua NH-L9i ?

L12S, not L9.tabascosauz - Tuesday, June 9, 2020 - link
Yeah, good luck with that. L12S already beats out the Black Ridge, the latter of which this one competes with. This company also loves overstating their TDP capabilities, unlike Noctua and Be Quiet.Valantar - Tuesday, June 9, 2020 - link
L12S is 70mm, this is much shorter, more of an in-between thing, though height-wise it's closer to the L9 than the L12S. There is supposedly a version coming in a few months with a slim 120mm fan on top, that would be more of an L12S competitor.Beaver M. - Friday, June 12, 2020 - link
Yeah, I have a L9 in my case, which still has a bit of air.I would have to check if this cooler would fit in, but it looks like it might.
A L12S will never fit, not even closely.

I actually like the design. By pushing the air upwards from the CPU and board, it avoids a key potential drawback of the cooler's low and wide design, namely blocking airflow from cooling other parts of the MB such as VRMs. Key question not answered by the article/press release: how quiet or noisy is it? Important for use in an HTPC, which is, for me, a logical use case.sharath.naik - Monday, June 8, 2020 - link
That is already in the market designed by Dan from A4-sfx. I bought it like last year.Samus - Tuesday, June 9, 2020 - link
I have a low-profile ID-cooling 1U cooler rated at 75-watt TDP, and the 54-watt Intel i3-4160 it is tasked with cooling regularly throttles back and hovers in the mid 80's under load in a climate controlled rack with the fan set to full speed.To put it bluntly, it's a poorly rated cooler.
My last rack build had a Cryorig C7 (47mm high so required a 2U chassis) rated at 100w TDP and had no trouble cooling i7-8700k @ 95-watt TDP in an identical environment, and it's worth mentioning the TDP-up of the 8th gen is like 20-watts higher than the 4th Gen used in the previous build.
