When watercooling a RTX card it is all about Z height, meet Alphacool's GPX Eisblock

When testing the new watercooler from Alphacool, designed for RTX cards, [H]ard|OCP made an interesting discovery, VRAM height is somewhat variable.  As part of their review process they always check how well the waterblock mates with what it is cooling, and as you can see below there is something a bit off with their test sample.

As it turns out, VRAM height can vary by up to 0.3mm, which may not sound like a lot but is enough to cause mating problems unless you spread thermal paste on like peanut butter ... which is not that good an idea.  The good news is that you can purchase thermal pads in varying thicknesses which you can make use of to ensure a proper mate.  You can check out their initial look now, or wait until said pads arrive and the full review is published.

"Alphacool has always made a great showing when it comes to water cooling our hot video cards. The company has recently updated its Eisblock series of GPU water blocks to include models made for NVIDIA's RTX series of cards featuring the Turing GPUs. We show you these new blocks and tell you about our first experiences with those."

Introduction and Cooler Overview

Introduction

Aquacomputer's Cuplex Kryos Next water block is aptly named, in that it is the next evolution of their award winning Cuplex Kryos block. The biggest functional redesign was with the internal flow dynamics of the block, changing from a pin grid design to a micro-channel design on the base plate.

Externally, they added the option of including their Vision display, which integrates into the front of the block and displays real-time statistics on coolant temperature and flow. The block we used for our tests did not include the Vision module but was an all copper design with nickel plating throughout. The base all metal version of the Cuplex Krynos Next comes at a price premium with an MSRP of around $100.00.

Note that the Cuplex Kryos Next water block comes with a variety of different configurations, ranging from an acrylic top to an all silver design. Because of this variety, the price can vary quite bit from the above listed MSRP. Adding the Vision module to the block can increase the price even more.

During the past year we have seen a lot of interest in the SFX small form-factor power supply market with more and more big-name power supply manufacturers adding new products on a regular basis. EVGA’s SuperNOVA GM Series includes three SFX form-factor power supplies: 450 GM (450W), 550 GM (550W) and 650 GM (650W). We will be taking a detailed look at the SuperNOVA 650 GM in this review.

All three SuperNOVA GM Series SFX power supplies are fully modular and certified to comply with the 80 Plus Gold criteria for high efficiency. The GM Series power supplies use a 92mm cooling fan that operates in silent fan-less mode (below 30% load) thanks to EVGA’s Auto ECO Mode fan speed control. The compact SFX chassis measures a mere 100mm deep and they all come backed by a 7-year warranty.

A little bit of power for a little bitty system

Tagged: modular psu, corsair, SFX, SF450, 450W, SFF

SFX PSUs are great for small form factor builds, at 4" long it will fit into those smaller systems and in the case of this SF450 from Corsair, the 17" long cables allow you to cleanly route them through the chassis.  This is an updated model, you can find the previously released SF450 still on the market and unfortunately for the 2018 model, it is about $30 cheaper. 

Is there anything to the updated model which justifies the increase in price? Check out [H]ard|OCP's full review for the answer.

1548377198us1pizj64c_2_9_l.jpg

"The Corsair SF450 SFX is, as you might have guessed from the "SFX" part number, a computer PSU built specifically with small form factor systems in mind. Corsair promises high power density along with "low noise," which are two qualities that many SFF builders are likely looking for. It also brings has Platinum level efficiency and is fully modular."

A real glass tiger; the Cougar Panzer G

Subject: Cases and Cooling | February 5, 2019 - 07:16 PM |
Tagged: tempered glass, Cougar, panzer g, RGB, atx, thin red line

If you lack fingerprints, or are simply in love with cleaning tempered glass then Cougar's Panzer G with glass on the front, sides and top is worth a look.  For cooling it comes with three 120mm RGBearing fans at front, which can be swapped with two 140mm fans or their radiator equivalents, with the same able to fit at the top, along with a rear and bottom 120mm.  Cougar also seems to have grasped the popularity of 2.5" drives as it holds four, compared to two 3.5" bays and the latter can hold the smaller form factor for a total of six 2.5" drives.

Head on over to TechPowerUp for a closer look

"The Cougar Panzer G is an upgraded version of the original Panzer which combines the benefits of the Panzer-S having additional fans with even more glass panels all around. All that without a crazy big price difference make the Panzer G quite the intriguing choice for those who are fans of understated looks and maybe a more professional work environment."

ASUS haven't put out a PSU in quite some time; which changed at CES when they showed off the 1200W ROG THOR PSU at their booth.  There is a lot to this PSU, from an OLED on the side which will display how much wattage is currently being drawn from it to a the huge assortment of power cables.  As you can see on the back, there are a dozen SATA power connectors in addition to eight 6+2 PCIe power connectors and extra 12V for your motherboard.  On the other hand, it is priced at over $300!

If the sticker shock hasn't finished you off, [H]ard|OCP put it to the test, and it did very well.

"ASUS is getting back into the computer power supply game in a big way. Today we have the Republic of Gamers Thor 1200 that promises to allow you to "HARNESS THUNDER."
