PANO-MOUNTS GPU Backplate Memory Radiator Aluminum Heatsink Cooler with Dual 70mm 4Pin PWM Cooling Fan for Graphics Card RTX 3090

Good morning,I installed this gizmo last night over Nvidia GTX with different mounting solution.I used 0.5 mm thermal pad and thin MIL spec nylon rope to secure heatsink in place.Result of the AIDA64 stress test revealed that temperature dropped approximately 7C at idle and 3-4C at high load depending on the time.However, besides this mod I also replaced thermal pads within the video card and applied high efficient thermal paste between GPU and the heatsink.So with that I am not giving 100% credit to this heat sink, however I do claim that it contributes well into video card temperature reduction. For that reason I gave it 5 stars.Hope this will help.Thank you for your attention & have a great day!

IT WORKED! The heat sync with the two built-in fans dropped my GPU temp by almost 10 deg Celsius! It was a last ditch effort before replacing the card & IT WORKED! Couldn’t be more thrilled with this purchase.

no thermal pad

Upon further investigation it product says it doesn't include a thermal pad but it's very well hidden there is also a list of the items in the box and a thermal pad is included, all in all the cooler does well for what's it's intended for, it cools the back of the card. Don't expect a 20 degree difference but easily a 4-7°C Drop in temps.

First off the metal is unfinished. You really need to use the gloves. Even with them I cut my fingertip twiceSecond off, the fan blades and plastics are very cheap. Be careful. They will snap easily.Thirdly... The cords used to adhere it to the back of the GPU are a pain to use and honestly suck to get just right. Once they are on there they work well enough.The temperature difference is probably like 2-4c if that.Really overall not worth the hassle in my case.Especially for the price and the fact it doesn't include a thermal pad.
