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.

if replacing the pads and paste won't void your warranty you can do so..the heatsink may also be not tightened down properly, preventng proper/good contact on the heatsink, either ways, you can try those solutions..

 

There's nothing much you can do to reduce the GPU hotspot except to replace the thermal paste with something better (assuming you continue to use the stock cooler). If you used liquid metal you might shave off a couple degrees but that's going to be about it.

You are almost 30C from the max acceptable which is 110C and are probably looking at a watercooling setup if you want anything below 75C gpu hotspot temp under full load.

 

When we talk about the GPU Hotspot aren't we referring to the Core? Not sure if this particular GPU uses a pad or a paste. In any case, have some good paste ready. Liquid Metal or something safer but effective with a Wm/k of 15 maybe.

There are videos showing how to properly apply LM. I've done it before following one of the advise from a guru here in OCN. Had to tape around the core prior to spreading the paste.

Another way of lowering the temp is to undervolt and test that uv with the games you play.

But 83c is fine for aircooled gpu. My GTX 1060 goes to the lower 90s.

 

GPU Hot Spot is the part of the GPU core that is the hottest. So lets say a game makes heavy use of Geometry, then the GPU hot spot might be the Geometry engines. The hot spot switches around the GPU as certain parts are more heavily used than others. It's not really a problem.

 

I lowered the voltage by 70mV and that lowered temps a few degrees. Not certain I want to tear the card apart for another couple of degrees.

 

Wise. Maybe a tear down if you keep the card past the warranty period. Playing with UV before hitting that point of diminishing return. I do it to both my 5700 and 5700XT and they actually boost a bit higher. Took me a number of hours to find the right balance until the games i play no longer act up.

I cannot afford the current prices of gpu so i went ahead and bought a waterblock for my 5700XT and make use of my water cooling parts just laying around. Looks like i 'd sticking to these cards for another year or so.

Enjoy your card.

EDIT: All the 6600s are sold out in the egg.

 

Got the gigabyte pro version, core / hotspot temp stock is a little bit better then yours like 50/70°C, but if i krank up the powerlimit the hotspot goes quite high even with high fan speeds while core stays low 39°C (cause high fan speed) but hotspot goes to 80+ anyone got a idea whats up with that ? 3dmark link with temp at 39°C but hotspot 82°C AMD Radeon RX 6600 XT Grafikkarten Benchmark Resultat - AMD Ryzen 7 5800X,ASUSTeK COMPUTER INC.

Completely normal. AMD GPUs are filled with sensors all over the core on various segments of the core. All this information is used by AMDs driver in order to control the clock speed, fan speed, voltages, etc on the fly. Plenty of clock gating going on (parts of a core whose clock speed goes down and/or voltage goes down in order to conserve power and reduce heat while offering more voltage and high clock speeds to other parts of the core that are in use). To calculate this, Temperature sensors are p[laced all over the core. Your "Hot spot" is the current most active part of the core. It's also the highest overall temperature recorded by a sensor.

Your GPU clock is an average of all of the temp sensors across the Core.

Perfectly normal for the Hot Spot to reach high temps.
