So I got a new mobo, CPU and RAM today, put it all together and it seemed to go off without a hitch. When putting computers together I figure that something always goes wrong and I guess I was correct.
When I put the heatsink on (stock AMD cooler, had compound pre-applied), after seating the cooler I went to seat the ram and realized I'd made the dumb mistake of seating the cooler the wrong way round (the cooler sticks out on the side with a big AMD label, which blocked the first slot for my RAM (though the manual has the RAM indexed in slots 2 and 4 for 2 sticks of RAM) I did however rotate the cooler to prevent future headaches if/when adding more RAM.
I've put my hand on the heatsink and it's slightly above room temp, definitely not sinking the 70c
I didn't think turning the cooler when the paste was still wet and not heated by the CPU would have an effect. Could it have or could there be an issue with the cooler or could it be that I ruined the (pre applied) thermal paste by removing the cooler, turning it 180 degrees and screwing it back down?

I do have different thermal paste (not of any specific brand) but it's about 10 years old (however it's still in the syringe and I tested a very small bit of it on my hand, still gooey.

What do you think the issue is? A cooler or motherboard issue? The thermal paste? Or some other issue?

Would ten year old thermal paste still be good? Should I try it if the temperatures don't change?

I've been using Hwininfo64 for temperature stats. The CPU is at 0-1% load.
Motherboard is an MSI B450 "Tomahawk"

Never mind the old thermal paste, just noticed I have about 0.1ml (or less) of it. Definitely not enough.

There's a (small) computer shop a five minute walk away so I'll phone them tomorrow and see if they have thermal paste, though no doubt they'll claim they don't, despite assembling computers in their back room.

Just to avoid confusion the plan is to clean the heatsink and CPU first, then apply the paste.
I'm assuming medical isopropyl alcohol wipes (70%IPA). You know, the kind that come individually packaged?

Also, it should be okay to have my CPU at 70c for the rest of this evening (I'll likely be awake for 3 more hours, then turn the PC off overnight) and possibly tomorrow evening if the people in the shop claim to have none; aka it's all in their back room and they couldn't be bothered inventing a price for a tube.

Thanks.
I'll probably go with eBay since newegg doesn't deliver to the UK (not that I recall anyway) and Amazon can take days to deliver whereas Royal mail "first class" almost always takes a day.
I've been playing it safe and turned the PC off, thankfully I have a smart tv and Netflix will keep me.entertained for one or two evenings.

I've heard horror stories of coolers literally ripping the CPU out of the socket and leaving a few mins behind in the socket. I would assume that common sense is a factor in this (though I don't think that the thermal compound has been on long enough, or has set correctly for this to happen) and that if the cooler is "glued on" I should try gently twisting it until it comes off; though if I'm getting temps like 70c idle I doubt there's a strong connection between the CPU and the cooler.
As well as that I thought the amount of coolant applied to the heatsink was extremely minimal (about the size of a 10p piece, or a quarter in US currency) directly on the heatsink.
The manual for the CPU said it would be enough and I guess it might have had I not done a 180 with the cooler (before powering on) however removing the cooler to reposition it showed that the corners of the CPU weren't covered in paste, only a somewhat smudged part in the middle.

Well, fingers crossed that they have thermal paste in the shop. I've been in once before (it's essentially a door leading to a counter with a.couple of cases on show and a few motherboard/gpu/CPU boxes.

I'll phone up and ask if they have any in stock if they say no I'll bluntly ask if they have any in the back room and I'll gladly pay them double the price they paid for it, so I don't need to order online and wait a day. Hopefully if I explain the issue and am polite they'll feel my pain and sell me a tube.

It was indeed an issue with HWININFO64.
I'd went out and bought a syringe of thermal paste (£15 for a 5ml syringe of the stuff), well; time to return it I guess. Lucky I didn't open the packaging.
My CPU is running at 20c according to Hwininfo, which would explain why the heatsink was barely warmer than room temp.

The room was about 16c when I updated the software. That's with the PC in my living room.
When I was a teenager I remember having the PC up in the spare room with no heating; used to warm my hands up off my Pc's case fans.

Glad to hear
Mine bounces 27-35c idle i think it looks at the different cores.
58c playing ghost recon with fans on h110i @balanced
And less if i set them to max.
I have replaced the stock corsair fans with the noctua 140mm 3000rpm fans. They are loud but work very well.
On a p95 small fft stress test 76c .max fan.

Many thanks crosslhs82, you likely saved me a massive headache and potential further issues such as ripping my CPU out of the socket due to the grip of the glue. Not to mention the money I spent on the new tube of thermal compound (I'll probably leave it back tomorrow with my head hung in shame; at least I never opened the packaging), I was actually feeling like the 23c (average) temp was incorrect, but I installed another program (Core Temp 1.13) to double check and they both give the same readings; I had read a thread on the Hwinfo forums about the temp being offset by 20c and
I tried to install AMD's "Ryzen master" but it claims a new version is already installed (which is apparently an issue AMD are working on as of December 2018) but AMD software has always required black magic and sacrifices to get working, so I wouldn't hold out for it to start working any time soon, unless I reformat.

The fact that you saved me from removing my cooler (likely while my board was in my somewhat dusty) case has saved me a LOAD of trouble.

The Hwinfo forum had a thread saying temps were offset by 20c on a Ryzen processor, hence the double checking with a different program. The CPU (PCEI) temp is set to 40c but it's 40c min, 40c max and 40 average; over ~12 hours. I assume this is a sensor on the motherboard directly below the CPU and is only activated above 40c, hence the constant temperature; at a guess; it would explain the constant temperature reading, despite the room warming up as I turned the heating on.

Anyway, I hope anyone else using Hwinfo reads this thread. Sees that I was fooled into thinking my CPU wasn't properly cooled and doesn't go down the route of heatsink removal like I nearly did.

I am really glad I checked back here before removing the cooler, you've done me a huge favour.

Thanks to everyone who offered info to help out and a special thanks to crosslhs82 who probably saved me endless hours of headache.

I'll remember to update monitoring software in future after this.

I turned on A-XMP (allowing my RAM to be clocked up to 2900mhz; the stock clock on the RAM was 3200 but I'm play with 2900, it only goes up to 3k with the Ryzen 5 IIRC anyway.
Turning on "gameboost" seems to have stopped my CPU from being throttled and my CPU is now running at 3.8 idle (which is odd) and temps are floating at around 35-40c with the stock cooler; if the temps go up really high I might consider a (closed system) "water" cooler as prices have come down enough to compete with standard air coolers.

Hi
1 check mobo for bios update
2nd gen board and cpu have better mem support.
2 what power plan are you running in windows.
If there is a ryzen balanced plan you have the updated bios.
Thats when mine showed up.
When on that plan under processor power management look at the fisrt setting min power state if not at 5% set it to that.
Cooling can be active or passive
Play with that 1 for your system see if there is a difference.
Then the last 1 max performance should be set to 100%.
Being a b450 mobo it should be able to run you ram at what it's rated for without any changes.
My mobo is asus rog strix x470 f gaming
My xmp is called docp
My ram is g.skill flare x 3200 and shows only 1 profile.
Down below that in bios is mhz settings set it to 3200 and it runs it.
Mine is currently set to 3400
I used typhon burner and ryzen dram calculator and set the fine timings.
The ram may have to be started in a new thread or send me a prvt message and i will keep checking.
