AMD Ryzen 5 & 7 CPU Cooler Round Up

Ryzen 5 1800X thermal testing

AMD Ryzen 5 & 7 CPU Cooler Mega Test

Thermal Testing

In this review, we have tested our coolers in a room temperature controlled environment and tested each CPU cooler with their stock fan configuration with their fans running directly from our system's power supply at both 12V and 7V (using fan speed reducers).  

Each cooler will be tested on Windows 10 using OCCT to provide a heavy CPU load for half an hour, where we will use Ryzen Master to record CPU temperatures throughout testing. The highest measured temperatures are recorded on the graphs below. 

Any CPU cooler that reached 70 degrees automatically failed our thermal test, though it is worth noting that no coolers reached this high threshold unless we overclocked our CPU. 

In our stock tests, we used 2666MHz memory, the highest that Ryzen officially supports, with our overclocked tests running at 3200MHz to provide more stress on the system. 

 

Why does the 1800X run cooler than the 1600X at stock? 

With Ryzen, we found that stock voltages varied depending on your model, with our 1500X running at 1.31V, our 1600X running at 1.28V and our 1800X running at 1.22V under 100% load using OCCT. This gave each CPU very different thermal results under load, with our 1800X presenting the lowest results due to the fact that it used the lowest core voltages at stock. 

These changes in voltages cause some strange results at stock settings, though it really does go to show the importance of fine tuning your CPU's core voltages when you want to control your load temperatures. More volts means more heat, so it is always best to use the lowest voltage that is stable. 

 

Stock 

At stock setting all of the CPU coolers that we have tested were easily able to cooler our Ryzen 7 1800X, even our £36.95 Cryorig H7, which means that Ryzen 7 systems can easily be built with budget-oriented CPU coolers.  

Moving up to our AIO liquid coolers we can see one common trend, that load temperatures would simply not decrease below 34 degrees while under load under OCCT. This is unsurprising since this is only 14 degrees higher than the room's ambient temperature.

It is clear that at stock setting most aftermarket CPU coolers will be adequate to run AMD's Ryzen 7 1800X, though that changes when we start overclocking.

Overclocked

For our overclocked CPU testing we ran our Ryzen 7 1800X at 4GHz with a core voltage of 1.4V and a SoC voltage of 1.1V. We ran the CPU with our memory kit clocked at 3200MHz and ran the OCCT to simulate a worst case scenario CPU/thermal load. 

In the below graph we can see that the Cryorig H7 has been taken off the graph, with the Noctua NH-D15S failing to keep temperatures under 70 degrees unless the fans were run at their highest speeds. It is clear then that heavy overclocks on our Ryzen 7 1800X will require an AIO liquid cooler to stay under 90 degrees without overly loud fans.     

We can see that by using larger liquid coolers that we can decrease the load temperature of our 4GHz R7 1800X to 60 degrees or below, with the largest 280mm liquid coolers like the Corsair H115i and the NZXT X62 providing the best performance.

Such a shame for a low temp limit. This kinda hurts the argument that AMD platform is cheaper right now since you need to invest into a strong cooler to maintain the OCs most people aim forQuote

But at the same time how many people overclock on X99 without a large cooler.

I do agree with you, raising the thermal limit with Ryzen 2 would be fantastic, as it could allow even basic air cooling to handle higher overclocks/voltages. If it were 80 Degrees I think even the Cryorig H7 would have passed OC testing on the 8-core.Quote

Thanks for all the work Tom and your helping hands, Was interesting how little difference between the 12v and 7v think I'd go for a little warmer quieter system.

Tbh I'd think if your looking at overclocking either Intel or AMD you'd most lightly look at an AIOQuote

I use the $25 Hyper T4 to cooler my R7 1700 at 3800-3900mhz @ 1.4V and it seems to work just fine, granted I've upgraded the fan to a 140mm High Pressure Venturi fan, but it's probably not too much better than the stock fan. fan ran at 100% RPM, controled by a Sentry Mix 2 fan controller, super handy to have btw

Rarely breaks 60C running in a hot shed.

I would highly recommend a deepcool gammax 400 instead though, as it has cut outs to fit RAM, i wouldn't be able to put RAM into the 1st slot if I needed to upgrade to 32GBs, since I can't turn the heatsink on AM4 anyways.Quote

most enthusiasts would, but not everyone will. Especially those people buying the 1600/x CPUs. Either way, spending all that money on a cooler hurts the "cheaper" argument people, including me, would use. It'll still end up cheaper of course than an intel system, but still more money is still more money.Quote
