i7-3930K CPU EK Supreme LTX

Welcome to my fourth i7-3930K series of CPU block tests, the EK Supreme LTX.   This is EK’s more budget friendly “Light XTreme” version of the Supreme HF.  So this is a lower cost option without a center nozzle plate, without the metal hold down plate, and without some of the premium accessories like back-plates.  After seeing the very favorable Supreme HF Plate #6 results on the 3930K, I was really interested to see how this lighter brother would do.

This sample was sponsored by EK waterblocks, thanks!



Quick Overview

EK-Supreme LTX (LTX stands for Light XTreme) is a universal Intel socket CPU waterblock for the advanced enthusiast users. It has been designed to lower the production costs yet still offer the EK quality branded CPU waterblock at the best price.

Product Description

EK-Supreme LTX is the direct successor of successful EK-Supreme LT which debuted in 2007.
It’s main improvements are:
better flow: due to improved channel depth design up to 10% higher flow compared to EK-Supreme LT
– better cooling performance

The EK-Supreme LTX cooling engine uses fin design. The water (coolant) accelerates through 46 very thin channels which provide extreme cooling surface area. Very thin copper base bottom wall even further improves cooling performance.

The base plate is made of electroless nickel plated (EN) electrolytic copper lapped and polished to +/- 0.0007mm flatness. The top is made of quality cast acrylic material.

CPU socket compatibility:
– Intel LGA-775
– Intel LGA-1366
– Intel LGA-1155/1156
– Intel LGA 2011

Enclosed in the box:
– EK-Supreme LTX series water block
– Classic CPU mounting mechanism

Please note:
– Due to superior nickel plating method and corrosion resistance, the waterblock may loose brightness over time and become of a bit duller tone.

I got this sample a bit over a month ago now and it does come with some LGA2011 hardware.  The specs also note how the LTX is an improvement in both flow and cooling over the LTX.  The one obvious difference I noticed in addition to the block is the lack of a back-plate for 775/1366/1155 systems, but that’s of no consequence to LGA2011 since you don’t use one anyhow.

    Would this do good on a I5-2500K?

    Awesome I’m getting one!

    What do you mean by “pressure too high” in first listed con?

    • Martinm210 says:

      After mounting many blocks many times I subjectively felt the mounting pressure using the instructions were higher than average. This can bow the block more than ideal and also puts nnecessary stress on the motherboard. I have killed several motherboards now in testing so I’m a bit more careful about putting excessive force on blocks. More is not always better when it comes to mounting pressure.
