Cryorig H7 not cooling right

Parts: Ryzen 1600x with a ASRock Taichi 370.
Cooler: Cryorig H7

Knowing I'd have to wait for an AM4 bracket for it that was on back-order I grabbed a cheap CPU cooler that was compatible out of the box. That cooler was the Deepcool Gammaxx 300 (20$)

Got it all running 3.8Ghz @ 1.35V after an hour of prime 95 the 300 keeps CPU temp 70C or less (peeks at 70 then hovers around 69.x mostly). I was excited knowing the H7 should be a better cooler.

AM4 bracket came in, installed H7. Same test, no change other than 300->H7. The H7 runs it at 76C under full load. I figure i'll remount it.

I unmounted it, clean everything, check it, remount it. Really tighten down screens to make sure there is no wiggle what so ever. I can see there is 0 thread left for the screws to go in to the HS, so it's physically as tight as it can get. 76 C...

Thinking i'm losing my mind, put 300 back on. It had came with pre-installed thermal compound. I use the Cryorig on this remount. 69C! Makes sense, the Cryorig thermal is probably better than pre-applied by 1 C.

Uninstall, remount H7. Same thing 76C +

I'm stumped. I've tightened, loosened, remounted, case sides on and off, etc. No change 300 always beats the H7.

Footprint of the HS is the same and I'm consistently using same amount of thermal between the too coolers. When taking them off the Deepcool looks well covered, the H7 looks well covered but seems to be thick towards the bottom side of the CPU compared to the top. This makes me think the HS is sagging a bit (can't visibly see it though). There is no way that thing is getting tighter though without me threading the screws or adding something under the back plate.

the H7 should be a better cooler. Has almost twice the cooling surface, rated at 140W TDP vs 130W TDP. However the 300 is beating it pretty handidly at same fan RPM, same noise level.

If it wasn't for the gamma fan being blue I'd throw the H7 out. The H7 looks nice and it should be better so I'm looking for suggestions on what is wrong.

Nothing wrong with 1.35 volts even running it 24/7 their people running it 1.4 and 1.45.

For the temps the H7 should be the better cooler I might consider they were to hasty trying to get out the back plates for it and might be a bit out of specks or the batch that was made was a bit out of specks.

1| What are your ambient air temps?
2| What is your chassis's make and model?
3| I don't think the voltages and clock speeds are healthy for your Ryzen platform. The voltages look high as well as the clocks. You should be below 1.3v IMHO.
4| There's also the placement of the fan, is it centered on the heatsink with the top edge of the fans shroud being in line with the heatsink's lip?
5| I assuming you've installed the cooler while the system was vertical...?

68F, 48% RH. Temp and Humidty guage is on my desk. It's same for both coolers.



Phantek 400S. 120mm provided fan in the back, two 140mm Phantex EXs for the front all running on high with the provided fan controller. I thought it might be an air supply problem took sides off, results didn't really change. (both got 1C cooler)

Appreciate the feedback and I will be trying to lower it in the near future. However. 1.35v is stock on the 1600x/Taichi. If I reset my bios it's set at 1.35v. General consensus is under 1.4 as long as temps are controlled.

Also it's the same for both coolers so if it's high, it's high for both of them and wouldn't explain why a 20$ cooler is beating the pants off a 40$ cooler


Yes. The 300 it's nearly impossible to mount the fan incorrectly as it as a groove and a lip on the top. The H7 fan and HS match in size and it's flush on all sides. Exactly as pictured on the box and their website.


The 300 was done horizontal as it has the clip style mounting and is infinitely easier to pushed down on it. The H7 has to be mounted vertical as you have to hold the cooler and the screws are on the back of the mobo. I could try mounting the H7 while it was horizontal but I'd have to make some sort of saw horse type rig, which I wouldn't think Cryorig would expect us to do, but I might try it tonight..
