Design and Installation
The HEX 2.0 uses a small dual tower heatsink design, with the 92 mm fan housed in the center.
The front of the cooler has the three required connections in one cluster, with PWM fan, micro USB (for software control), and PCIe power.
Looking from the side you can see that the cooler is not much larger than the 92 mm fan within, and you can see there are four heat pipes for each plate, with the lower plate (this side) allowing the HEX 2.0 to function as a standard air cooler when the TEC functionality is not needed.
The base of the cooler is flat and nicely finished, and you can see the retention screws on either side.
Opening up the fan housing reveals a removeable 92 mm fan, which is connected via a standard PWM header inside. This allows the user to use any compatible fan if desired.
The included fan is a
Sanyo Denki San Ace 92 (model 9S0912P4F011). This is a 92 x 25 mm design with a max speed of 2650 RPM, max airflow of 44.5 CFM, and max static pressure of 0.120 inchH2O.
Installation
Installation of the HEX 2.0 is straightforward, with the type of retention mechanism familiar to anyone using recent designs from Noctua and others. The platform is quite sturdy once in place, and the HEX 2.0 simply screws down with two captive screws located at the bottom of the unit, accessible with the fan cover and included 92mm fan removed. Once tightened down the HEX 2.0 feels very solid, and should provide excellent contact with the CPU surface.
The backplate, which supports Intel and AMD installations, has rubber pads on the surfaces that contact the motherboard.
The installed cooler occupies a small footprint that did not interfere with any components on my EVGA Z170 Stinger mini-ITX motherboard.
Next we will have a look at the performance results with the HEX 2.0 cooler.

How does it deal with condensation on the TEC?
The design objective and
The design objective and proven in operation is that you will not see any condensation with the HEX 2.0 unlike previous TEC based coolers. That is the benefit you get out of our Intelligent Control of the Active/Passive operation.
Don’t worry about it, this
Don’t worry about it, this thing can’t even cool the proc below ambient at idle.
How would it lower temps
How would it lower temps below ambient if the TEC only turns on at high thermal loads?
That would be the worst time
That would be the worst time for it to run. At high thermal loads, a TEC would only add more heat to get rid of. Anyone who designed such a system clearly knows nothing about thermal transfer.
So, I’d avoid anything they designed like the plague it is.
“I would love to re-test the
“I would love to re-test the HEX 2.0 with an overclocked AMD Ryzen CPU to see just how far a little 95 mm cooler can take a processor like the R7 1700, but that will have to wait”
No it needs to be done ASAP for those that are looking at the 1700’s best savings for the overclocker’s money! Maybe it can be done when some of the tweaked Motherboards arrive with faster DDR4 memory support. Also test the RX 580 Polaris refresh with any builds for an affordable build option with that 1700’s overclock potential and affordable sweetspot of a price/performance metric.
If I could have purchased a
If I could have purchased a motherboard I probably would have already. Now that I've waited this long I might just go with an R5 1600/1600X instead. And the MSI X370 Gaming Pro Carbon I've had my eye on is still out of stock as I type this…
Well yes try the R5s along
Well yes try the R5s along with the R7 1700 with this cooler SKU for some overclocking benchmarks.
And what do you make of any 16 core/32 thread Zen/workstation SKUs using these rumored(1) chipsets? I’d love to see any 16 core Zen/Worksttation SKU benchmarks on the single socket ASUS X390 motherboard(?), and remember that for Zen/Naples the Infinity Fabric was supposed to offer an NVlink like ability to connect up more in a direct attatched GPU fashion to any Vega radeon Pro WX/instinct SKUs that will also make of of the Infnity Fabric IP. So there will probably be a 16 core Zen/Workstation variant on an MCM module with some of that extra Server/workstation IP on the MCM module. I do not think there will be any 16 core Ryzen/consumer branded SKUs.

I saw thermoelectric in the title and immediately decided I had traveled back in time. Who on earth uses Peltier’s to transfer large amounts of heat at or above idle temps.
*ambient, not idle. Excuse
*ambient, not idle. Excuse me
No one. They’re way too
No one. They’re way too inefficient to move any reasonable quantity of heat. For every Watt they remove, they generate several more. Clearly that’s not going to scale beyond a dozen Watts or so. So, yeah, it may cool down your idle part below ambient, but what’s the benefit of that? Worse yet, they will act as insulators at load.
Peltier coolers will always
Peltier coolers will always (unless someone has a really incredible breakthrough) have a COP (Coefficient of performance) below 1.0, meaning they will always consume more energy than the heat they remove.
The only possible way of actively cooling (by active I mean not just pumping a secondary fluid to reject the heat) computer components is to use refrigeration cycles. The problem is they are far too complex to make it worth it so far. And it’s hard nowadays finding a refrigerant that is reasonably ecological and safe to use.
Absorption and adsorption cycles can also work, but require a large setup. And if noise is a concern then maybe thermosiphons will work, I’ve heard of a company using a thermosiphon to cool a pc with no moving parts required, but it was expensive and relatively large since it requires large heatsinks to condense the fluid.
@Sebastian.
I’d love to see
@Sebastian.
I’d love to see temp graphs combined with dB information…Not sure how that would work without causing info overload.
It could be a great way to get a complete picture of how each cooler performs without having to look at temp and dB graphs to figure out which cooler suits you best.
I’ve toyed with combined
I've toyed with combined graphs in the past with mixed results. That's an interesting idea, however – have not attempted combining noise/temp data like that before. If it made sense visually and was on a fixed scale it could work.
I’ll stick to a Noctua DH-15
I’ll stick to a Noctua DH-15 thanks, This might do a decent job, but it’s inefficient and you need to run it insane mode to achieve decent cooling when OC’d. No thanks.
I cannot see using this thing
I cannot see using this thing in a PC because existing methods are good, and because I am scared of what happens if power too the Peltier element were to fail under load.
However to cool very high power LED systems used for horticulture or large area lighting it could be extremely useful.
While idea is certainly
While idea is certainly interesting it has potential to be a catastrophic. When powers go down, CPU will be fried in no time at all.
If you really want tower cooler standard constructions are much more safe and proven.
And make no mistake. I’m all for innovating things, but practically comes first. Couple fans on tower cooler work perfectly well. Thank you.
I’ll definitely be trying
I’ll definitely be trying this out in my next build instead of a AIO, thanks.
Was the NOCTUA fan at maximum
Was the NOCTUA fan at maximum RPM?
This was the main confusing thing I noticed. If the Noctua fan had more RPM available then perhaps it could close the gap (not that it needs to for THIS exact OC as it’s well within temp).
Don’t understand this design,
Don’t understand this design, if its supposed to turn on when its needed then it means that the heat dissipation of the heatsink cant keep up with the processor and in that scenario the TEC just adds more heat.
TEC isnt viable anymore due to its inherent inefficiencies. A TEC element is a set of XxY smaller heatpumps where each specific pump is limited in how much it can handle. To manage the loads generated by modern CPU’s the size of the element needs to be very large and it’ll be a beast in power/heat.
