3700x temps

[theone8181]

So I've had the stock cooler in and off a few times now (which is a pain in the area BTW). My temps are idling in the 60vs, although they don't seem to change much. I couldn't put new paste on as I don't have any (only using what was on the cooler). Do you guys think it's purely that, when I first put it on the temps were mid 50's. Using the Ryzen master software, the temps keep bouncing all over the place, although i don't know if that just lists the hottest core?

Yea, this was all last night and also a bit of squeaky bum time. Just done some benches and im ranging from 38 upto 76 degrees with the fan on high. I assume the hi/low just limits how fast the fan spins, as at times it stops.

That's true, I'm not sure if I've got pbo on. I'm coming from a 2600k so this stuff is a bit new to me.

It just seemed hot to start with, i think even hotter than my 2600k. I'd like to think that when i add some new paste it will be better.

Which part of the UK are you in to get ambient of 35 in a room? Oh scratch that you meant CPU temps lol. I'm idling low 30s on stock cooler, with ambient around 23ish. There's a lot of stuff running that causes it to though.

Please touch the end of the heatpipes on your coolers (if it's stock or air) during CPU full load and tell us if yours are hot ?

There are reports that some batches of Ryzen have poor heatspreader implementation, too deep machining or contact issues for correct heat transfer from the chiplet.

How hots hot, (i've no idea what temp they should be). I'd have thought idle temp and load temp would be enough to tell you if alls ok.

I got two 3700X together. One idled at 29C, the other at 39C. Under any load the 2nd one would just hit 89-92C before hard throttling and performing like nutsack. The first one would hit and hold high clocks at ~72C and slowly start heat saturating the stock cooler over time. It took 2hrs to hit 89C with Aida64 Stress test going.

The 2nd one was basically DOA for any viable use case and has been RMA'd. The first clocked to 4.5GHz with manual overclocking of the CCX's. If I had only got one, diagnosing the crap one would have been a much more laborious process.

I'm assuming though, that the it should be night and day like that. One think I was surprised at was that the cooler isn't a very flat surface, I'd have thought a better cooler would be a flat copper block with the pipes pressed into the back.

I’ve gone from a Corsair h115i platinum to a Noctua nd-h15 chromex edition the whole ltt limited edition pushed me to get it

Not exactly cheap but paid 89.99 for it from Noctua official outlet and got to say I’m really impressed.

my h115i on my3900x under extream benchmarks was around 80-85 degrees and under full fan load the fans was noticeably noisy would t say as bad as older auto but defo noiseier then I would like

my Noctua on testing was about the same temps and very similar all core boost speed also but a lot quieter then my h115i was you can bearly hear it at in my phanteks elvov x case.

I also really like the look of a massive heat sink and this all black Noctua looks amazing altho with both fans on it doesn’t play nicely with my Corsair vengeance pro rgb the ram is to tall. But ordered some new ram to solve that problem and sold my Corsair stuff on eBay.

but at the end of the day the really big air coolers like dark rock pro and nocutua d15 will match a lot of aio out there and beat so many of the cheaper aio

From what i've seen, due to the heat being generated in such a small area (rather than the bulk of the chip), it doesn't seem to make much difference to temps what cooler you use. FWIW i'm using the standard prism cooler on a 3700X and it seems ok. At idle im in the low 30's and if i startup something like battlefront 2 i average about 70. Benchmarking seems to go to 75-80, however i've set a custom fan profile to make it quiet.
