After nearly a year from first announcing the Cu line of full copper coolers PC cooling innovator CRYORIG is now releasing the C7 Cu copper enhanced SFF ITX cooler. The C7 Cu is built from the award winning C7 architecture with one obvious upgrade, the extravagant use of copper for the whole heatsink body. By exchanging for a full copper build from aluminum has allowed the C7 Cu see improvements of up to 15% in thermal performance. The increased thermal performance without increased size is a key advantage of the C7 Cu especially in ultra compact SFF/ITX builds where space is limited.

Aimed at solving the space limits of Small Form Factor ITX systems, the C7 Cu was set with the task of further improving performance but without increasing size or fan speed. Utilizing higher thermal conductive materials was the only answer for the C7 Cu. Copper is nearly twice as thermal conductive as aluminum but nearly three times as expensive. That's why copper is normally only used on the most thermal critical components such as heatpipes and heatsink base plates. With the C7 Cu, CRYORIG has swapped out the aluminum elements of the C7 with pure copper. Thermal performance gains are close to 15% when compared to the original C7.



Built on the original C7 architecture, users can except to get the same features such as Zero Interference design on both Intel and AMD boards, included installation tool, and pre-installed 92mm PWM fan with integrated anti-vibration pads aimed for SFF/ITX systems. The 92mm fan features CRYORIG's Quad Air Intake system, with additional intakes are placed at the four corners of the fan. This allows the fan to pull air from the sides not just from the top, because in most SFF/ITX systems there's limited space for air intake between the top of the heatsink and the case side panel.

The C7 Cu is set to release in mid to late April in Asia and late May to early June in the USA and Europe. Pricing is set at MSRP 49.95 USD (-tax) in the USA and 49.95 (vat incl.) in Europe.

Woohooo! Back to 2006 brown, finger-stained styled coolers!!
 
More then double the weight and 66% more expensive for a <15% better cooling? Hmm...
 
Nice to see it happen I suppose. Had already given up waiting for the Cu version and picked up the standard C7 a couple months back.
 
Full copper never worked as intended.
Takes a lot of time for a fan to dissipate the heat out of the fins. Stick to aluminium, Cryorig.
 
Copper is the most beautiful thing in the world.

Most copper heatsinks are coated to prevent them from oxidizing, this would definitely affect their performance
 
The coating does some impact, The most of it comes from copper's inability to release it so quick like Alu does.

I think you have wrong idea about thermal conductivity(TV).
A material with high thermal conductivity will relase heat quickly, then a less thermal conductive material.
Copper has TV of 401, Aluminium has TV of 237.
Transferring same amount of heat Aluminium will store 1.69 time more heat than Copper.

In a normal tower without that much demand for cooling sure. But in a SFF build (upt to ...)15% better colling might be worth the investment. Ofc proper reviews are needed at this point to check the claims.

A great example of this is the TRUE120. There was a copper version of it and it performed similar or worse because of that. The amount of conventional air that came through it couldn't release the heat fast enough into the air. This isn't about what thermally conducts better, but how it can handle air cooling

I would say that a copper heatsink would be good when you push a nice amount of air through it

If you are thermal throttling sure, but then again if you are throttling with a stock CPU with the regular C7 variant, your case choice might be questionable.

If that is not the case and you are overclocking, then SFF might not be the best form factor for that.

On regular use I would rather buy a small tube of Kryonaut to use instead of the bundled TIM and call it a day.

Link please about TRUE120.
 
If I wanted a upgrade cooler (well really mandatory) on say that ASRock DeskMini GTX1060 that was just reviewed this would be a nice pick.

I think copper will release heat better overall, but it's a juggle; as to how thin they want and to many the fins, how they interface them to the tubes and slug, how close they pack them, and ultimately how much air they can pass through that. Honestly, it takes much more time and dedication to manufacture, higher cost in materials... so yea this price is higher for the gains presented, but in this compact form/noise etc. is there a better performing H/S with a better cost?

Here it looks like they just ran the same gauge, number of fins and interface copying the aluminum fin in copper so with that this is all you really get 15% for change nothing except to copper material in the fins.

Others seems to find it on par or a little bit better than the normal version.
I'm guessing that calling it "worse" was not right on my part. But, the difference for the cost, insane weight and more just didn't make sense
As I said higher thermal conductive material will dissipate heat better. In that review, Copper Ture120 was better than the Aluminium by 2°C.
But can agree about the price. Not paying 50%+ more for 2-5°C better temperature.

So we need better air flow/fans as compared to the aluminium version. I don't see how Cu models wouldn't be better, with appropriate cooling.
The fan for this is barely doing 40CFM so a little extra air (flow) could go a long way in making the cooler shine.
 
well played CRYORIG, make full cooper of one of their simplest and low performer coolers, nice play indeed !

Bring on 2006! That raw CU is legit :)

Back on topic, I would love to see how this performs in a Dr Zaber Sentry and 2400G

It looks like a low profile cooler for those who want to fit a decent cooler that doesn't take much space.
 
Id like to see an Ashura Copper from Scythe, or a Macho Copper from Thermalright.
 
The reason why the C7 was chosen to get the Cu treatment is specifically because of the size/height limits of SFF/ITX builds. Naturally going full copper will not be as cost efficient as per say choosing a larger cooler with more fins and heat dissipation area. But given that there's no space to do that in SFF/ITX PC's, choosing a more costly, higher heat conductive material is a trade off that seems to make sense. If you're buying a C7 Cu to cool a full ATX Tower... I don't think you're making the right choices, but thanks for supporting CRYORIG!
 
They still need to make an adapter/fanclips for the C7 so we can use different 92mm or 120mm fans.
