Package Content: 2 X CPU Water Cooling Block Review: Works fine! - Haven’t had any leaks. I took an x-ray because i wanted to drill and tap two holes to mount a couple of MOSFETs and I didn’t wanna accidentally drill into one of the coolant channels. It turned out the coolant channels inside the block were too narrow for screw size I wanted to use. I used super sticky thermocouple tape instead. I could probably still drill, and when I hit the cooling channel I could immediately stop drilling, tap the hole, and use a very short screw so that the screw doesn’t block the cooling channel, then add some locktite or rtv to the threads, but I did the lazy thing and used the thermal tape, lol Review: Only rerecived 1 instead of 2 - The parcel took long time to deliver. I'm happy with the quality, but the parcel only contains 1 cooling block instead of 2. ## Features - ★ Water cooling block size: 40 x 120 x 12mm; Material: aluminum alloy. - ★ The surface of the water cooling block is polished, the inner flow channel is extruded into an M-shaped flow channel, brazing parts into a whole. - ★ The pagoda nozzle has a minimum outer diameter of 7mm and can be connected to an inner diameter of 7-8mm Water pipe. - ★ This water cooling block applicable to computer CPU, graphics gpu heat, motherboard, xbox consoles cpu, graphics, semiconductor cooling piece, industrial inverter driver, laser head cooling and industrial control cabinet cooling. - ★ Package Content: 2 x Aluminum Water Cooling Block. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Z3JH98S | | Brand | DIYhz | | Compatible Devices | Desktop | | Compatible devices | Desktop | | Cooling Method | Water | | Cooling method | Water | | Customer Reviews | 4.6 out of 5 stars 315 Reviews | | Item Dimensions L x W x H | 12L x 4W x 1.2H centimetres | | Manufacturer | DIYhz | | Manufacturer Part Number | 10245-2 | | Material | Alloy, Aluminum , Silver | | Model Number | 10245-2 | | Power Connector Type | 2-Pin | | Power connector type | 2-Pin | | Product dimensions | 12L x 4W x 1.2H centimetres | | UPC | 757233296242 | | Unit Count | 2.0 count | ## Product Details - **Brand:** DIYhz - **Compatible devices:** Desktop - **Cooling method:** Water - **Manufacturer:** DIYhz - **Material:** Alloy,Aluminum,Silver - **Power connector type:** 2-Pin - **Product dimensions:** 12L x 4W x 1.2H centimetres - **UPC:** 757233296242 ## Images ![Aluminum Water Cooling Block, Liquid Water Cooler Heat Sink System for PC Computer CPU Graphics Radiator Heatsink Endothermic Head Silver 2pcs(40mm x 120mm x 12mm) - Image 1](https://m.media-amazon.com/images/I/71jRAtZIGJL.jpg) ![Aluminum Water Cooling Block, Liquid Water Cooler Heat Sink System for PC Computer CPU Graphics Radiator Heatsink Endothermic Head Silver 2pcs(40mm x 120mm x 12mm) - Image 2](https://m.media-amazon.com/images/I/61ZYyjU1mAL.jpg) ![Aluminum Water Cooling Block, Liquid Water Cooler Heat Sink System for PC Computer CPU Graphics Radiator Heatsink Endothermic Head Silver 2pcs(40mm x 120mm x 12mm) - Image 3](https://m.media-amazon.com/images/I/61RcmPqy5mL.jpg) ![Aluminum Water Cooling Block, Liquid Water Cooler Heat Sink System for PC Computer CPU Graphics Radiator Heatsink Endothermic Head Silver 2pcs(40mm x 120mm x 12mm) - Image 4](https://m.media-amazon.com/images/I/61rYGuBd45L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works fine! *by A***O on 24 November 2023* Haven’t had any leaks.
