CRYORIG A40

[crazyeyesreaper]

The A40 by CRYORIG is the company's entry level offering in their all-in-one hybrid liquid CPU cooler lineup. It lacks the size of the A80 and the radiator thickness of the A40 Ultimate. However, unlike the others, it offers a more affordable price point with all the same features.

"Optional airflow fan feels gimmicky"

Try turning it off and see if it influences anything I guess, then we know whether or not its a gimmick

Sorry, couldn't live with that angled fan, aesthetically it looks terrible to me, not an issue if you have a non windowed case I guess, but I do, and I wouldn't want to look at it on a daily basis, yes I know you can remove it but that then leaves an ugly looking block with wires everywhere.

That fan on the block IMO just screams Cryorig couldn't keep up with the competitions cooling so they had to add another fan to help out. Aesthetics of it are awful. A plan circle and logo would look a lot better also I'm sure it would have been cheaper.

Perhaps the little fan provides airflow for the RAM?

Would it not have been more beneficial to point that small fan towards the heatsinks? I remember when i was OC'ing my FX8320 it was the only way i could keep stable at higher voltages. I actually jury rigged a corsair ram slot cooler to those vrm heatsinks lol.

I did its in the conclusion a couple of degrees on the VRM. System memory used doesn't get hot its Gskill DDR4 2133 MHz. Even then temps on the VRM at best 2'C typical change was 1'C. Intel mainstream platform the VRM on a good board does not really get hot enough to matter.

DDR4 2133 with no heatsinks. Memory doesnt get hot to begin with. Do you really think a fan pointed directly at said typical memory will make no difference?

Typically speaking except in rare situations ie ultra extreme frequencies memory temps are not even worth considering. DDR4 just doesn't get that hot and I have seen lower temps from just plain removing the memory heatsinks themselves. Half the time its all show and no benefit.

Yes an FX8320 it would likely make a difference an overclocked 8320 is similar to the 9590 and is a 200+ W TDP CPU in some cases approaching 300w.

300w vs an Overclocked 6700k that might pull 100w. AMD motherboards from that era were also rather cheaply made in terms of VRM with many boards having weak VRMs. Thus the issue. Intel Mainstream platforms use so little power its a non issue.

AS such heres an excerpt from the conclusion.

The hybrid airflow fan is a great idea; however, in my testing, it did not contribute all that much in terms of reported temps. Sure, the VRM section was a few degrees cooler, so it does work, but it didn't really make a difference. On Intel's mainstream offerings, the CPU might get hot, but power draw is still so low that it makes the extra cooling feel a bit gimmicky and unnecessary most of the time. There are, however, instances where it can make a difference. In those situation, such as with SFF and HEDT systems or extreme memory, it likely will have a far greater impact.
