Used 4 of them per card, 2 on either side of the gpu on the backplate. These with fans pointed directly at these heatsinks have kept my mem junction temps from throttling at 104c, down to a steady 88c to 90c without having to do thermal pad mod. I only recommend this as a temporary fix, as I was only waiting for my favorite thermal pads to come instock. Temps after thermal pads were 84c without these heatsinks, 78c with them! Review: Be careful ... - 3M 9448A Tissue Tape is NOT a good thermal conductor. As heat-sinks go, this is fine. Simply, a chunk of metal to regulate heat; easy. The tape on the back is intended to give the layperson the confidence that it will adhere and conduct heat away, but the tape on the back of this is really a hinderance that, if left, will degrade the conductivity of the heat-sink. Why bother putting tape on the back unless it was designed to conduct heat? 3M 9448A is double sided tape; nothing more and will act as a thermal insulator rather than a conductor making this heat-sink less effective if not useless. Don't trust the tape. Peal it off. Clean it off completely, and apply a quality, purpose built, heat conductive tape or paste ... paste is better. I'm more than a little disappointed that I have to clean a seller's lame attempt at cheap appearances to compete where the pictures show the heat-sinks are clean with no tape. Having said that, it's simple. It's a chunk of metal that dissipates heat. In that regard, it's fine. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08JSLBHD7 | | Best Sellers Rank | #2,096 in Heatsinks | | Brand Name | DGZZI | | Cooler Heatsink Material | Aluminum | | Customer Reviews | 3.6 3.6 out of 5 stars (20) | | Item Dimensions L x W x H | 1.57"L x 1.57"W x 0.79"H | | Item Weight | 0.05 Kilograms | | Manufacturer | DGZZI | | Mounting Type | Panel Mount | | UPC | 725983610106 | ## Product Details - **Brand:** DGZZI - **Cooler Heatsink Material:** Aluminum - **Item Weight:** 0.05 Kilograms - **Mounting Type:** Panel Mount - **Product Dimensions:** 1.57"L x 1.57"W x 0.79"H ## Images ![DGZZI 40mm Heatsink Kit 2PCS 40 x 40x 20mm Aluminum Heat Sink Radiator Cooler Cooling Fin with Thermal Conductive Adhesive Tape for Cooling 3D Printers CPU Light-Emitting Diode Power Active Component - Image 1](https://m.media-amazon.com/images/I/61CR7F2kJEL.jpg) ![DGZZI 40mm Heatsink Kit 2PCS 40 x 40x 20mm Aluminum Heat Sink Radiator Cooler Cooling Fin with Thermal Conductive Adhesive Tape for Cooling 3D Printers CPU Light-Emitting Diode Power Active Component - Image 2](https://m.media-amazon.com/images/I/61+ILauQQ7L.jpg) ![DGZZI 40mm Heatsink Kit 2PCS 40 x 40x 20mm Aluminum Heat Sink Radiator Cooler Cooling Fin with Thermal Conductive Adhesive Tape for Cooling 3D Printers CPU Light-Emitting Diode Power Active Component - Image 3](https://m.media-amazon.com/images/I/5148xI7c-WL.jpg) ![DGZZI 40mm Heatsink Kit 2PCS 40 x 40x 20mm Aluminum Heat Sink Radiator Cooler Cooling Fin with Thermal Conductive Adhesive Tape for Cooling 3D Printers CPU Light-Emitting Diode Power Active Component - Image 4](https://m.media-amazon.com/images/I/51jGx23fCQL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for RTX 3090 gpu's *by A***A on May 10, 2021* Perfect for the back of my RTX 3090 cards in my mining rigs.
