GIGABYTE Radeon RX 6600 Eagle 8G Graphics Card now $179 after Promo code

I will have to install HW monitoring software to answer your question. What HW app are you using to check temperatures?
I'm using RadeonSensor.kext and RadeonGadget app. I have also tried HWMonitorSMC2 and Macs Fan Control. HWMonitorSMC2 are bit buggy?, but show watt usage: 3W with one monitor and 20W with 2 monitor. So card get hotter with two monitors, I don't know its the watt usage or memory clock which causes the high temperatures, but others have said AMD cards with two monitors using memory clock at full speed. Before with RX580 the temps were between 45 and 55 degrees with two monitors in my system.

Dual monitor temperatures for Signature/ 300 Series-3 rig:

Using V.0.3.3 SMCRadeonGPU.kext, RadeonSensor.kext and RadeonGadget app my Signature/ 300 Series-3 rig idles at 53-55 degrees and spikes to 60 and 75 degrees with Geekbench 6 GPU Test. What temps do you get with GB 6 GPU Test?

Thanks for info about RadeonSensor - installed and ran flawlessly.

That's ok idle 53-55, staying there for long? the GPU fans are not spinning? Before mine creeps up to 70 degrees. Two days ago I have modified my casefans, two fans pointing straight to GPU, after that, GPU slowly go up and up to 60 degrees and stop there idling. (with two screens). Geekbench spikes 80 degrees for a short second, and little 71 degrees and down to 55 degrees. My GPU fans are spinning when reacting 70 degrees, and stop 55 degrees. Others with 6600 no RX, saying fans start at 60 degrees, perhaps XT is 70 degrees. Here are watt and memory clock 5 minute after turning on computer with one monitor, 15 min later with two monitors. Its huge difference in watt and memory clock

Back again, 179.99 ! after the ten dollar off promo code. These are energy efficient and quiet with normal use.

Remember that this is a 3 fan, very long card. Need the room in your case to use it.
Some mATX cases may be too small for it to fit. Below is a pic in an ATX case.
