I'm using Ryzen 9 3900x with its stock prism cooler. after 5 minutes of prime test the temperature reaches up to 80 degree celsius. Do you think I should get a tower cooler?

Only if the 3000 RPM from the cooler bother you (noise). Thermally you are okay. The CPU is reaching its default 95A current limit.

I change the paste with Thermalright Heilos. The temperatures are higher than before but; the drawed current is also higher than before. Why is that?

Current increases from 95A to 106A.. That is weird..

Honestly those temps are totally fine. Get a new cooler if the noise bothers you.

Temperatures are higher becuase power draw is higher.

I know, but I realise that even I do the same prime test after/before, the power draw is higher than before. What could be the reason?

2 reasons: Could be your better thermal paste allows the processor to boost a bit higher - Or could be because that thermal paste is a worse and the processor is running hotter, so algorithm decided it needs some extra volts for stability (hotter = more voltage needed).

Looks like your clocks are a bit higher than before so it's likely reason 1 - but hard to say unless you see the clockspeed as well.

Don't forget the CPU will auto adjust based on temperature, power, and frequency with cooling typically being the first limit you will hit. Otherwise the temperature is fine if you are ok with the fan noise. After your thermal paste change the CPU is allowing itself to consume 10 more watts than before so you're getting 10 more watts contributing to heat.

I also realised that in the second occasion the fan speed has lowered.

This was how I applied the ptm yesterday. Could the small trace/artifact on the right side cause this temperature problem?

What temperature problem? If your repaste is better, your cooling will be better, the CPU will request more power for more performance because it can, up until the temperature reaches a certain threshold where the CPU will stop boosting and/or you reach your default power limits. You can use PBO to fine tune your CPU to rebalance and lower temps if you want. With my 5950x lowering EDC a little bit knocks down temps a little bit. Another way to go about it is to keep your default power limits but use PBO to simply reset the temperature limit to your desired max which is also very effective.

If your cooling allows you to reach your PPT limit before reaching 95c your good. We are only talking about 142W.

That's probably 3x the volume of paste you needed. It needs to be a thin, see-through film, not a mass that will insulate the CPU from the base of the cooler.

It's ptm thermal pad

get the fire extinguisher ready! HAHAHA:p

>with its stock prism cooler

ok, but not for the x900x cpu.

just bought a used peerless assasin for $20 yesterday. will knock down at least 15 degrees

Maybe not the best but Wraith Prism works fine even with my 3950x. I think I got mine with the 3800x.

I just wanted to test previous compound and the new compound with the same settings. But I see that due to specific character of cpu, that could be quite challenging (like Heisenberg uncertainty principle:))

Ah, a pad. Never tried them before.

Actually it is a phase changing pad. After 43 degrees of Celsius, it transforms into liquid state.

Doesn't seem to be doing a good job anyway. TPU's review got better thermals with a Noctua cooler (and presumably no special pads/paste).

hows your 5950x? happy? what do you do with it?

LOL which one? My original that I fried is still doing great no issues, it turned out my NR200P motherboard must have went bonkers with instability so RIP on that build because the CPU works just fine in the same motherboard replacement for that one. The replacement CPU I got for the fried one in case it was really damaged is ok. The replacement backup B0 stepping one I got from ebay with a X570 Taichi Razor (for an amazing price at the time) is amazingly better at hitting higher boost clocks per core than the B2 stepping of the other two. The reason I ended up with so many is I had to make sure I had a stable PC and stable backup PC on hand in case of failure for work reasons. It took awhile to diagnose the original chip was really ok and not degrading so in the end I ended up with a dedicated gaming PC which previously was just standby parts in case of failure.

The original fried CPU is in my portable gaming PC ML-09B, the replacement for that one is in my non-work daily with my original X570 Taichi, and the B0 is in my now VM server X570 Taichi Razor. They are now sporting NH-D9L coolers with AM4 offset mounting (which are working great) with the exception of the one in ML-09B which runs a little hotter. I swapped the 011D out with a 7950x in my work daily for a killer discount back in September last year. Fast forward 6 months later and 9950x is just starting to drop to $400 on ebay now and then with the 7950x dropping to sub $350, and I question if I should have waited just a little bit longer, however B650 Live Mixer is harder to get now especially for a good price. So I have no complaints and otherwise saved $350 on a motherboard with the PCIe lane and slot configuration I was willing to live with but comparatively sucks even at the high end AM5 to a decent X570 AM4.

A 9950x would complete my 16-core stamp collection where I would be willing to sell off my 5950x's (keeping my original chip for sentimental reasons in the ML-09B) but because AM5 sucks in expansion slots I can't consolidate my two non-gaming 5950x systems with a single AM5 system - at least for now.

The 3950x sporting the Wraith Prism (in my Abit i8) was essentially replaced by my 5950x X570 Taichi Razor system but will soon be repurposed for Linux duty so I can figure out if Linux is a good fit for me as Windows 10 becomes obsolete near the end of this year.

what do you do with the 5950x?

usually gamers dont buy this cpu but more for productivity

and what cooler do you use for the 5950x?

I just bought this for video editing at christmas sale. I didnt want to go am5 as MB and ram prices are double for am4

im curious if there will be a last cpu series after 9950x before they change the platform

Work. Usually in VM's.

After the pandemic I had to ensure I had backup hardware after being forced to work from home so I build a 2nd PC with the same CPU and used it as my gaming rig with the expectation if a disaster occurs with my daily (which is/was water cooled) I would just need to swap or teardown the gaming rig as needed. Using the spare parts as a gaming rig ensured I test them so I know they would work in case of an emergency if my daily wasn't functioning.

I've used several. In my work rig I've tried a monoblock (before that motherboard went up in smoke), Velocity, and Velocity2 water blocks all which worked well enough. Initially I had Wraith Prism on it for a short time but noise reduction was my goal after that hence the move to water cooling.

After swapping into 7950x I'm using NH-D9L (with Noctuas AM4 offset mounting kit - included) on my 5950x's. They are for compact for 3U server cases and get the job done however not as quiet as 120mm coolers, and probably not as effective as bigger coolers, but those machines are on my rack/shelf now many feet away instead of being next to my desk, so the noise is not an issue and of course they will run hotter than bigger coolers. I'm getting my full frequency range so it's not concerned. I got the NH-D9L's because they were compact for my cases which already have good airflow and also managed to snag them for discounted price at the time.

My ML-09B build uses the NH-L12S with the 5950x but that is a very specific build so it was pretty much the only best option I had available which ended up being a 99% perfect fit but can be noisy under full load (but not annoying) and runs a bit hotter under full load than NH-D9L.

When my 5950x was in my NR200P, there I used the NH-C14S which was a great fit for that case and got the job done as an intake even with a single fan. That cooler didn't have offset mounting kit at the time (maybe still doesn't) but I borrowed the unused offset mounting parts from my NH-L12S kit and made it work by flipping the bottom mount upside down (if I recall correctly) and it happened then to come into alignment with the NH-C14S mounting screws. I'd say the offset mounting kit did improve the performance of the NH-C14S. Like with the NH-L12S the NH-C14S was my choice very specific for that case design. I don't think it would do well in a typical mid or full tower case.

There are better air coolers than the ones I used so keep that in mind.

I am wondering this as well. Either way I'm always looking for the discounts and managed to snag some great deals from ebay.

Update. After using 1 month, the temperatures are in check, and even improving. I've never used such a great compound before. Both CPU and GPU are not throttling anymore.

Here is what I used for both GPU and CPU:
