Nvidia RTX 4090 Graphics Card Review

Temperatures

Thermals are a key point to any GPU, as it allows it to boost for a prolonged amount of time and depending on the task that’s being performed, thermals can be either higher or lower.. Lower temperatures in gameplay are a good indication we can overclock the card more. Higher temperatures mean the graphics cards are likely not hitting their peak boost clocks long enough and may need more cooling or even underclocking.

So cooling wise, we did see slightly higher temperatures on the MSI card at 74 degrees on the hotspot, while the Gigabyte card came in slightly lower at 71 degrees. These are both a little higher than the 3090 Ti which came in at 70 degrees, but still falls well below any cause for concern. I guess that new TSMC 4nm process really does help, given the extra performance. Could you imagine if this was still using Samsung’s 8nm process? Toasty!
