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: Seem to be solid and will do the job. - Seem to be solid and will do the job. Time will tell how well they hold up in actual use but working for now. ## 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 | | Best Sellers Rank | #79 in Water Cooling Systems | | Brand | DIYhz | | Brand Name | DIYhz | | Compatible Devices | Desktop, Gaming Console | | Cooling Method | Water | | Customer Reviews | 4.5 out of 5 stars 364 Reviews | | Item Dimensions L x W x H | 4.72"L x 1.57"W x 0.47"H | | Manufacturer | DIYhz | | Material | Aluminum,Alloy,Silver | | Material Type | Aluminum,Alloy,Silver | | Model | 10245-2 | | Number of Items | 2 | | Part Number | 10245-2 | | Power Connector Type | 2-Pin | | Product Dimensions | 4.72"L x 1.57"W x 0.47"H | | UPC | 757233296242 | | Unit Count | 2.0 Count | ## Product Details - **Brand:** DIYhz - **Compatible Devices:** Desktop, Gaming Console - **Cooling Method:** Water - **Manufacturer:** DIYhz - **Material:** Aluminum,Alloy,Silver - **Number of Items:** 2 - **Power Connector Type:** 2-Pin - **Product Dimensions:** 4.72"L x 1.57"W x 0.47"H - **UPC:** 757233296242 ## Images ![40*120*12mm Heatsink - Image 1](https://m.media-amazon.com/images/I/71jRAtZIGJL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works fine! *by A***O on November 24, 2023* Haven’t had any leaks.

Time will tell how well they hold up in actual use but working for now. ### ⭐⭐⭐⭐⭐ Good quality, no issues *by K***R on July 4, 2023* Purchased two of the sets. We use them connected to our chiller to a cooling die for parts coming from an injection molding machine. They are solid, no leaks and very uniform. We used hose straps because we are pushing pressurized chilled water but held up good. Three of them are pinched between two ¾” aluminum plates, they keep the entire fixture at the chiller temp even after hours of use. ## Frequently Bought Together - DIYhz 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) - HiLetgo 2pcs Water Pump 240L/H DC 12V 4.2W Micro Brushless Pump 3M Pumping Head Ultra Quiet Water Pump for Pool Aquarium Fish Tank - Clyxgs Water Cooling Radiator, 12 Pipe Aluminum Heat Exchanger Radiator with Fan for PC CPU Computer Water Cool System DC12V 120mm Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/223058188-40-120-12mm-heatsink](https://www.desertcart.fr/products/223058188-40-120-12mm-heatsink) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-08-12*
