Cooler for 7090
I have acquired a 7090 MT with an i7-10700 and I would like to upgrade the CPU cooler from the generic one to something that would give me just a little more cooling. I'm thinking about a low profile Noctua (want it to be quiet), but I do not want to have to remove the board to add a backplate. Any suggestions? thanks!

Noctua cooler requires use of their backplate. To use Dell backplate w/o need to remove motherboard you can upgrade from generic 65W pancake entry level heat sink to the 95W tower Dell cooler for 7090.

VWD01 is for XPS8940
I think performance wise the two coolers are similar.
Some vendor advertise with inflated “tdp” spec.

Got the Deal4Go unit and installation was easy and it is not noisy and is making a significant difference in my core temps. I now have two Noctua case fans, the tower cooler, a low-profile RTX card, and of course a PSU. The only noise I hear that I would, as a someone sensitive to fan noise, call a little unpleasant is coming from the PSU. Buying a new one hoping to get a quiet one is a real shoot and I'm not going to try. The tower cooler is pretty dang quiet and barely spins at low temps. Between it and the extra case fan I shoehorned to front of the case my graphics card fans spin less loudly when gaming. Maybe the extra flow through is keeping it cooler. Overall a very nice experience upgrading the cooler. I run Core Temps and had overheating protection set at 95C and with it enabled the machine was going to sleep. Now the temps are no where never that. Problem seem solved.

@redxps630 Thanks for that. A search leads me to the first entry for this on Amazon:
Deal4GO CPU Cooling Fan Heat-Sink Assembly 2NW0M VWD01 Replacement for Dell XPS 8940 OptiPlex 7090 7080 7071 MT G5 5090 5000 Tower Desktop, Black
This looks to me to be fanless. Am I right or maybe I'm on the wrong track.

@CEG3 Never mind. I see the fan now.

I did eventually track down the actual Dell model using the 2NW0M part number you provided on eBay for less money, but I would wonder if it is as quiet (potentially) or a good quality as the Deal4GO unit at 125W and higher maximum revs.
thanks again for the help!
