The GeForce RTX 3090 Founders Edition runs sizzling, as we came all the plot by closing month when we reviewed NVIDIA’s flagship GeForce card. Whereas NVIDIA has outfitted the Founders Edition with an innovative cooling solution, it struggles to chill the cardboard’s 24 GB of GDDR6X VRAM. In our assessments, as an instance, we measured hotspots of 84 °C all the plot by the VRAM, which is within Micron’s 94 °C height working temperature.
Nonetheless, Tom’s Hardware recorded the VRAM reaching 110 °C, an unsustainably excessive temperature. Unsurprisingly, the cardboard downclocked tremendously to mitigate these temperatures and end its VRAM from overheating. A YouTuber called CryptoAtHome has found a solution, though.
As the video beneath presentations, replacing the inventory VRAM thermal pads with third-celebration ones dramatically improves thermal performance. In step with CryptoAtHome, their Founders Edition card would possibly perchance well maybe lope at a excessive reminiscence clock whereas sitting at roughly 85 °C. Sooner than the modification, the VRAM in CryptoAtHome’s Founders Edition card moreover reached 110 °C.
One would possibly perchance well maybe potentially build an even greater temperature bargain by the use of superior thermal pads. CryptoAtHome venerable Thermalright’s Odyssey Thermal Pad, which has a 12.8 W/mk thermal conductivity rating. By disagreement, Thermal Grizzly’s Carbonaut Thermal Pad is rated at up to 62.5 W/mk. As commenters maintain identified, Fuijipoly Extremely Gruesome XR thermal pads at 1.5 mm thickness would possibly perchance be a greater alternative. These are rated for 17.0 W/mk of thermal conductivity. Alternatively, one would possibly perchance well maybe diagram end a personalized RTX 3090 that cools its VRAM greater than the Founders Edition does.
