Ryzen 2700x and Cryorig H7 Plus cooling problems

Hey all, hoping to get some insight as to if I'm running in to limitations of hardware or there's some user error happening here. While far from my first build, it is my first time playing with a Ryzen so I'm not sure if I'm expecting too much or fouling something up.

I've just built up a Ryzen 2700x system (specs to follow). The request from the friend who's paying for the system was, amongst other things, for it to be quiet. Since the stock Wraith Prism cooler has been reported to be pretty noisy we decided on the Cryorig H7 Plus. Figuring between a push/pull fan configuration on the cooler and a TDP of 150w that this would be enough.

Now as for the problems...

Mounting: Mounting initially went as expected once I figure out the weird motherboard backplate the Gigabyte puts on the X470 Gaming 7. Pulled the stock AMD backplate off the motherboard, put the Cryorig Xbar backplate in it's place and continued on in normal fashion. I've installed a number of H7's before without a problem so the awkward holding the cooler in place and screwing it in process wasn't anything new. However once fully mounted and screwed down I noticed a lot of rotational play on the cooler. You could push it and it'd swivel a bit in place. The mounting backet is firmly locked in place on the screws, there's no play there at all. It's the heatsink itself thats swiveling on the pivot point of the mounting bracket. I hadn't noticed that before with previous H7s but I kind of chalked it up to a possible issue with the thermal paste (CRYO-Paste CP7) and cooler having not set or something in a cooler redesign that came with the updated model. To be sure I wasn't doing it wrong I've reseated the cooler 3 times now, cleaning and reapplying compound each time.

Temps: At idle it seems to be fine, running about 30c. However when I started stress testing it I ran in to high temps very fast. Prime 95 (v26.6, small fft) got in to the upper 80's before I stopped it. Prime does get hot so I figured I'd try other tools. Running RealBench I got the same high temps, this time spiking in to low 90's. Not once in all this have I gotten a crash or error, just really high temps. After running benches, the CPU runs idle in the 40's. These temps repeat with the case closed and with panels off. The fans on the cooler are ramping up with temp, so they are doing their job but something does not seem right. In previous builds with the single fan H7, I'd never gotten a system to spike this high. But those were with various generations of Intel i-7's.

So anyone have some ideas? Am I fouling something up or is the hardware just not up to the job?

The Ryzen 2700X with Precision Boost 2 will hit the 70/80's degrees with small FFT's. I know Ryzen use to show temps 10 degrees higher reading the TCl temp but not sure if that still is the case...hopefully someone else can jump in on that...
 


Ryzen 7 2700x being an 8 core cpu it's normal to run at high temps...all of the high core count cpu's run hot. My stock clocked (I am running XFR2) 2700x hit's 80c all the time when I load the CPU at 100%...and that's on water.

I personally would not feel comfortable with a cpu cooler that moves around though...the Wraith cooler AMD provides has pretty strong clamping force and I dont remember it moving at all when I tried it before going to water.

Just so you know...on air cooling my 2700x was maintaining an all core clock of 3.9ghz at 100% load even though AMD only promises 3.7ghz. Since I moved to the AIO 240mm setup it stays above 4.1ghz on all cores at 100% load.

Thanks for the input guys.
VMax - I've been looking in to the offset thing. When I use HWinfo I'm getting different Tctl and Tdie temps. Tho in my case only a 10° difference instead of the 20° I've seen quoted with the 1st gen chips.

Dorsai - I've only been getting 3.9Ghz on the cooler so far as well. Tho it's good to hear others are hitting high temps as well. I was hoping to avoid AIOs just because the person this build is going to is unlikely to notice any issues unless it makes noise. Which, if a fan bearing goes bad on an air cooler, is pretty easily known. But from the sounds of it I may have to look at going to an AIO with this build. I'm going to try out the wraith tonight and see if there's much of a difference.

the 2700x under PBO is about 180watts for TDP
stock 2700x is rated at 105watts but boosts to 140watts(XFR on)
found my hyper212 push/pull getting saturated with heat under PRIME and unable to recover
switched to a cheap AIO watter 120mm, which stabilized under load to about 60c Tdie

FYI: AIOs have fans and fan bearings. They actually have more moving parts and greater chance of failure than a decent air cooler.
 


I would not right of AIO's as they have come a long long way and a decent 240mm AIO of any of the major makes from Corsair, NZXT, Cooler Master, Fractal design and the cheaper variants in the Deepcool and ID cooling will do a very good job. I personally have been using AIO's since the beginning when the very first Corsair one came out and have yet to have any issues with an AIO and most important, love the consistancy of low temps without having a huge chunck of metal hanging of my motherboard...Like with most things, understanding what you are buying for and your use case is key but they are not prone to falling apart. Also they do cool very effectivly....Unlike an Aircooler which can last indefinitly and only requires a fan change or TIM change, an AIO does have a life span and I replace roughly every 3 to 4 years...just something to take into account.

Thanks for all the input everyone.

wifiburger: Those numbers make a lot of sense. I was seeing the H7 and the stock cooler just not being up to the task, so it's not very surprising.

vMax: I agree, the main reason I was hoping to do air cooling was since this system is not for me but for a friend who likely wont think of the life span of his cooler. Trying to plan around other people making the build a bit harder.

In the end I ended up going with a Corsair h115i Pro for the cooling. A little overkill but with the sale price it was worth it. The system is now running nice and cool. Benchmarking/stressing with RealBench and Prime95 keeps everything at no more than 62° and usually in the 50s at any given time in the testing. Now to work on the memory timings.. but that gets to be a new post.

Thanks for your help everyone!
