Because I couldn't calculate the proportions beforehand, my cooler (AK620 Digital) can't fit both fans, only the middle one. Will that one fan keep the temps good for a 7800X3D?

It seems that DeepCool does not list a TDP handling capability for the AK620 Digital either on their website nor in the product manual.

However based on independent product reviews such as Gamers Nexus, the AK620 places near the top of highest performance air coolers, even when the fans are noise-normalized for quiet operation. Running only one fan you may have to adjust the temperature curve to ramp up fan speed sooner, however it seems the cooler itself is plenty capable of handling the heat load from the 7800X3D.

Seems like CPU Cooler Manufacturers are not posting the TDP Ratings of their products any more.

Normally I am able to locate the TDP Ratings in Retail Advertisements or reviews.

Found this review that mentions the TDP Rating of your CPU Cooler: https://www.eteknix.com/deepcool-ak620-digital-cpu-cooler-review/

DeepCool AK620 DIGITAL features six pieces 6mm all-black heatpipes with raised copper coldplate to maximize heat dissipation to overall 260w TDP which supports even overclocked CPUs for mighty gaming performance. AK620 DIGITAL carries a thermal paste in package, please apply it on after removing the protective film of coldplate.

If you can only fit one Fan see if that is enough to prevent your CPU from overheating under stress by using OCCT stress test.

If the CPU reaches overheating temperatures above 89c then switch out the fan and install a HIGH CFM Fan with a rotation around 4000 -5000 RPM. That should help quite a bit in cooling your CPU than using a regular CPU Fan.

AMD recommends you use a AIO Liquid CPU Cooler for this processor since it has such a high TDP Rating of 120 watts.

Since your Air CPU Cooler is rated at 260 watts it should be sufficient enough to prevent the CPU from overheating under heavy loads but I imagine with more than one fan attached though. So you will need to see if one fan is sufficient or not by stressing the CPU and checking the CPU Temperature.

From AMD Specs concerning your CPU:

Default TDP: 120W

Recommended Cooler: Liquid cooler recommended for optimal performance

Max. Operating Temperature (Tjmax): 89°C

"Achieve peak performance on your CPU with substantial cooling capacity for high frequency overclocking. The AK620 features a maximum heat dissipation power of 260W and improved airflow to lower temperatures during demanding system applications." - Taken directly from DeepCool's website.

Ah yes, taken directly from DeepCool's website, 5 months later.

Thanks for the update.

Might want to consider an undervolt, although I'm sure there are special considerations for the X3D: https://www.youtube.com/watch?v=FaOYYHNGlLs

I found a pretty easy way of determining the capabilities of coolers that don't list the TDP.  Not to mention the fact that TDPs are just bad numbers. Take a look at Noctua's CPU compatibility page. They have a rating scale for their air coolers. Then find someone on YouTube that's done some cooler comparisons that includes your cooler and at least one other Noctua cooler. You can then see where you're cool or falls relative to the knock to a coolers and get some idea of how effective it will be with a specific CPU.

There's no standard in the industry, so you have to read between the lines with some brands. It has 260W of "heat dissipation power". Nowhere does it say TDP, which means that it probably would have a difficult time with a CPU TDP of 260W. With air coolers making such a big comeback, the industry really needs for it's customers to be able to have a way to compare one brand's product to another, perhaps they could put heatsinks in an oven that maintains a standardized temperature and then use the amount of time it takes for each heatsink to become heat saturated, as well as how long they take to passively cool back down to room temperature. It would be something that the brand could opt into. There could be a logo for the independent testing facility along with a rating system that correlates with the test results. getting just a few brands on board could potentially lead to more brands joining if the rating system proves to be popular with customers, every other brand would follow suit and then it would be just like the PSU rating system. I actually just looked up who issues 80 plus ratings and what I just described is almost exactly what CLEAResult did, and they're the only ones who can issue an 80 plus rating so they can charge whatever they want. It sounds a little bit monopoly-like. Just a wee bit.

Gbaii, I strongly doubt it. Worth a try, then consider buying a cooler that fits. There are many replies but none from you. Post a screenshot of Ryzen Master (RM) running Cinebench R24 running Multicore (image of RM ONLY). John.
