## Overview

The Modtek Silence D5 Pump is a high-reliability, magnetically driven industrial-grade cooling pump designed for professional PC liquid cooling systems. Featuring a silent operation, 1100 L/hr max flow, and low 18W power consumption, it boasts a 50,000-hour MTBF thanks to its single ceramic bearing design. Compatible with all major D5 reservoirs, it offers plug-and-play installation for efficient, durable, and quiet cooling performance.

## Description

ModTek D5 Silence: Advanced Cooling System Pump is a high reliability, high pressure industrial pump featuring a 50,000 hour MTBF. Modtek D5 reliability is afforded by the unique design of this pump, which contains only one moving part. The magnetically driven spherical impeller spins on a single ceramic bearing, thus extending the life of this pump beyond existing standards. The pump is completely plug-and-play, and connects directly to the computer power-supply with a standard 4 pin power connector. It's compact design and quiet powerful motor make it ideally suited for heavy duty cooling in environments. Works with all XSPC, Alphacool, Swiftech,Thermaltake, EKWB, Bitspower products and reservoirs that use D5 pumps.

Review: Solid quiet D5 pump - I took a chance on this particular D5, because it was considerably cheaper by about 40-60% It has a 2-pin header and a Molex pass through, so make sure you have a Molex to Sata-MALE (very important!) adapter. Being a 2-pin this is a DC not PWM pump. In my opinion, having the coolant flow run at a consistent speed is better than a PWM controlled pump that slows down/speeds up depending on requirements of whatever you are doing. Coolant is coolant, and with a reservoir to provide thermal mass, the temperature fluctuation curve is not going to change as quickly as the speed of a PWM pump, so constant flow rate is my preference. It comes in a plain box, no instructions or any stickers on the motor itself, its black polymer body, and thats it. Its quiet and has very little vibration. I will be recommending this to colleagues.
Review: Your standard D5 pump - runs well, if a bit loud - Interestingly my unit is loud in a high pitched pump-noise way at >70%, and also loud in a rattley way <45%. Which works fine for me since I keep it at 50-60% - moves coolant fast at that speed and has a dull barely audible hum. Compared to other brand D5 pumps that cost twice as much if not more, this is totally acceptable performance for the money. Happy customer!

## Questions & Answers

**Q: Is the speed adjustable via pwm or manual speed dial like other d5 pumps?**
A: PWM=no dial...

**Q: I see 2 pins in the pc fan connector. does that mean this pump is pwm?**
A: The pump is not PWM.  One connector for power the other is for pump RPM.

**Q: How is it possible that this pump only uses 18w?  all other d5 pumps use 37w and flow 1200l\h.  doesn't make sense.**
A: Didn’t care what watts being used. Just the price is cheap enough. Moves the coolant like any d5. Over 6 months used daily at 10+ hours with no issues.

### ⭐⭐⭐⭐⭐ Seems to be running just fine
*by L***D on February 9, 2020*

Seems to be running very good for the past month its pretty quiet. Not silent but not crazy loud. I'm satisfied with it for half the price of most pumps.
