Aurora R11, VRM heatsinks covering missing component?
I opened up the case of my R11 to see if there were any VRM heatsinks before installing a liquid cooler for the CPU and noticed that there are some missing components on the motherboard. The L shaped heatsink would cover this area, but there's nothing to cool. In the R11 manual, the motherboard is shown to be missing these components too, but I've seen other pictures of opened R11's with the VRM heatsinks that clearly has components under there.
Could anyone shine some light as to why some boards have some and some don't, and if I'd damage anything by installing the L-shaped heatsink over the empty part? I can see some solder contacts, I'm worried that placing the heatsink over it would possibly short them out.

It looks like connection contacts for (from top to bottom) two mosfets, two chokes, and four capacitors.
I can't say whether that is utilized in an Aurora with a VRM heatsink or alternatively if it is unused real estate reserved for future revisions of the motherboard. Intuitively I would imagine they don't manufacture two different versions of the motherboard for concurrent distribution. In the past, there was 1 version of the motherboard, and the difference was whether or not the VRM heatsink is added. I can't say on the R11 whether K-class CPUs also get those added mosfets/chokes/caps.
As an aside, the VRM heatsink is added to the motherboard if you purchase an unlocked CPU in the PC. It is required for the additional heat dissipation for OC.

Thanks! That picture of the underside of the heatsink cleared it all up. I thought that both parts touched the motherboard, I can see from the blue tape how it works now.

Hi, have you found a solution for vrm heatsinks? I'm new to the forum. I have the same problem.

If you ordered your system with an 10700 and later want to upgrade to a 10900k, can you then order the liquid cooling system and VRM heatsink to go with it?

If you want an Intel i9-10900k, it would be better to order it that way now.
Also get the Liquid-Cooler and the 1000w PS.

The blue pad is a heat transfer pad.

You should not expect a plain heasink without thermal pad to work.
The circuit is between the 2 screws it acts like a jumper and thats how it knows if the HS is there or not.

1. Liquid cooler, $109, part MH0HN
2. VRM heatsink (R11), $143, part N1C1D.
Contact Dell for current pricing and availability though.
Note, the R5-9 VRM heatsink (J46J2) is not compatible with the R11.
So yeah, if you want it buy it at the time of purchase. It will be costly to upgrade later. You can add liquid cooling when you configure/order the R11 from Dell.
