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!
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.
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
– 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.
