I picked up the above RX 6600 XT at Micro Center on the 11th for $399. Because this card just hit the shelves I downloaded the latest beta of HWiNFO64 today. After running Microsoft Flight Simulator for an hour at 1440p high preset maximum temperatures Celsius were:
GPU Temp = 62.0
GPU Memory Junction Temp = 56.4
GPU Hot Spot Temp = 83.0

I know those are within tolerances however I would like to get hot spot temperatures down. Would thermal pads help, and if so what type and thickness do you recommend. I have looked for a teardown of this card however, haven't found any yet.

Also, the card has a back plate for support only. There is no thermal pads on the back side of the GPU to connect it to the plate for heat dissipation. Again, would thermal pads be of benefit and if so which ones and what thickness.

Thank you in advance

I think hot spot temp is the hottest spot on the gpu die. Maybe thermal paste is what you should be replacing…

thermal pads on the backplate would help the memory chips and the vrms more than it would the gpu die.

That's one reason I was thinking about trying to move some of the heat from the die to the back plate. Just not sure if it can be done. Replacing the thermal paste on the face of the die might help. Not sure if the card was properly torqued for optimal heat transfer. Lots of questions.
 
Is the 6600xt worth it? My Microcenter has them in stock. I just had bought a 2070 that was used for more money, haven’t even installed it yet tbh, but I’m considering trying it out and tossing the 2070 back on eBay and picking up one of those powercolor cards.

This benchmark shows the 6600xt consistently outperform the rtx 2070 at 1080p.

but apparently it’s a very good, power efficient gpu for mining. About 55w at 30+ mh/s for ethereum according to a reddit post, 75w according to a tom’s hardware test...

So stock and current price might not last long… :( better act quick.

It depends upon what you are going to do with it. 1080p gaming is good with medium to maximum settings. I primarily wanted this RX 6600 XT for Microsoft Flight Simulator at 1440p. With High settings I get 60 to 70 FPS in aircraft by Microsoft on a sunny day. I get 44 to 50 frames per second in cloudy weather using a Carenado Piper PA44 twin engine, Carenado aircraft are more demanding. I have not played Call of Duty Modern Warfare yet, but other people are getting an average of 145FPS at 1440p Ultra settings.

The 6600xt butts heads with a 2070Super at 1080p without DLSS or R/T. If you enable those, the 6600xt gets stomped, pretty hard. The gap widens for 1440p and the 2070Super dominates the 6600xt at 4k.

But here's the kicker. It's basically a Gen4 card only. It's only got x8 pcie enabled by hardware, so at pcie4.0 x8 it's good, same as pcie3.0 x16. But, if you run Gen3 cpu/mobo like any Intel prior to 11th Gen or older Ryzens, the the card only runs at pcie3.0 x8, or same as pcie2.0 x16 bandwidth.

Between that and its 128bit buss, it's pretty much the same overall performance as a 5700xt, which costs about the same, if not cheaper, and only gas the advantage of R/T capability (if you call 30-60 fps an advantage, dropped from over 120fps)

If you have no gpu at all, it's a bonus, you can actually get something, somewhat reasonable too, but otherwise it's honestly no better than a 2070Super/1080ti/3060ti/5700xt

The kicker for me, I paid 600 for the 2070. I can get the 6600xt at msrp.

Gen3 cpu/mobo. You'd basically get the same bandwidth as pcie 2.0 x16, which really hasn't been seen since the GTX500 series, on a pcie buss that hasn't really been used in 10 years or more, everything runs at least a 192, with the stronger cards running 256 at a minimum.

Think driving a Porsche on only 2 cylinders...

Looks good, runs good, comes with a warranty, even drives ok, but if you stomp on the gas then be aware that grandma in a minivan is going to pass you..
