#nvidia #rtx3080 #rtx3090
In some use cases of intense VRAM usage, such as rendering, 3080 and 3090 GPUs such as the Founders Edition may exhibit cool GPU core temperatures but 100% Max fan speeds due to hot VRAM. Let's discuss some possible fixes such as thermal pad upgrades.

00:35 Is your Nvidia RTX 3080 or 3090 Vram thermal throttling?
01:02 While rendering a video, my fans went to 100% BUT the GPU was under 70C Core
02:08 Fan speeds were ramping up according to the hot VRAM, HWINFO update can now see the Tjunction max temp
02:38 The issue does not happen in most games, unless it's intense Ray Tracing games, but rarely happens
03:08 Issue appears when VRAM is being pushed - such as rendering, mining, and not as much in gaming
04:03 People using rendering apps and mining were the first people to run into this issue
04:31 Igor Labs had writen about this issue months ago
05:33 Which GPUs are effected? 3080 FE and 3090 FE for Sure
05:53 Thermal Pads on the GPU are the key to this
06:04 EVGA 3090 FTW3 shows in Precision the Vram temps, they seem OK under 80c, so these not affected
06:32 Air Cooled 3090 FTW3 62c GPU Core, vs Hybrid Cooler 3090 FTW3 52C GPU Core, VRAM not as affected and maybe 3-4C difference
07:30 Is your GPU Affected? What are the solutions and what can you do if you're having this issue?
07:59 Another solution, undervolt, reduce power or memory speed depending on your app, may not reduce performance that much
08:17 Running fans on high help reduce VRAM temps, but at the cost of high noise
09:08 Upgrading and replacing thermal pads on the back of the 3080 or 3090 may be helpful
10:08 Water Cooling your GPU will also help - even active cooling backplates for the 3090 are coming from EKWB
10:31 Conslusion - if your use case ramps up the VRAM temps and fans, consider thermal pads or other options to improve it
