Model: 31010 Review: perfect d5 block - This is BIS in my opinion. For a single loop its cool, fast, and fits perfect. Its large for a mid tower but you can see i put it in the bottom of a phanteks mid with a 420 rad on an eatx299 9800x chip so it can handle anything. the next pic its running that build through a thermaltake double stack cube9 snow case i made and up into that 420 nemesis gtx rad. i have it with the aquacomputer d5s but any 25 watt d5 would work fine like primochill or for less head maybe the 15 liam li's could be ok. it has great heat dissapation as you notice both my builds face it away from direct flow with the motherboard so it can dissapate out the case on another line. This is my second one and it will go where the first did, bit this time it will run a loop through a new Gtx 420 nemesis rad on a 10600k chip to OC. The second case does have a second loop in it powered by twin d5s on an acrylic bitspower block. These heatkiller blocks are durable well polished pump blocks with a nice O ring. Youll need tube caps but it has good options for them, and good mounts. ## Features - The HeATKILLeR D5-TOP is the perfect add-on for D5 pumps - Four G ¼" threads allow for easy integration into the cooling loop - Pump and fittings not included - Ability to be installed with a 90 Degree variation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071XP2BSY | | Best Sellers Rank | #1,742 in Water Cooling Systems | | Brand | Watercool | | Compatible Devices | Desktop | | Cooling Method | Water | | Customer Reviews | 4.7 4.7 out of 5 stars (8) | | Date First Available | June 21, 2015 | | Item Weight | 13.8 ounces | | Item model number | 31010 | | Manufacturer | Watercool | | Material | Stainless Steel | | Maximum Rotational Speed | 1800 RPM | | Noise Level | 50 Decibels | | Number of Items | 1 | | Power Connector Type | 4-Pin | | Product Dimensions | 3.15"L x 2.56"W x 3.15"H | | Voltage | 12 Volts | | Wattage | 25 watts | ## Product Details - **Brand:** Watercool - **Compatible Devices:** Desktop - **Cooling Method:** Water - **Material:** Stainless Steel - **Maximum Rotational Speed:** 1800 RPM - **Noise Level:** 50 Decibels - **Power Connector Type:** 4-Pin - **Product Dimensions:** 3.15"L x 2.56"W x 3.15"H - **Voltage:** 12 Volts - **Wattage:** 25 watts ## Images ![- HEATKILLER® D5-TOP (31010) - Image 1](https://m.media-amazon.com/images/I/61wrAD3eqmL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ perfect d5 block *by M***T on October 7, 2020* This is BIS in my opinion.
