7800x3d TEMPS
hi guys, first my system

7800x3d
7900XT
Asus Tuf b650 gaming plus wifi.
ddr5 6000mhz corsair dimm cl30
be quiet 850w
NZXT Kraken 360 Aio.#
Lian Li Lancool 216 case
Bios Updated last version


my "problem"

in Cinebench my Temps are going Instantly to 86*-88*c is this normal??
idle temp 45c*

the plastic cover is removed.. i tried 3 different Thermal paste pattern. the "butter toast" a Line
and a drop in the middle. temps are same +- 1*c
using thermal grizzly hydronaut paste.

my friend have a 280mm Aio and reaches MAX 81*c with the same settings

my pump runs at 100%
Aio fans spins also 100% at 70*c

i have 2x 160mm fans INTAKE

the Aio is mounted on top with fans blowing out of the case

PBO curves are done 2best cores at negative 30, all other cores at negative 25
expo enabled.

somone have a solution?

or is it the thermal paste? should i use a Arctic Mx6 or noctua nt-h2?

i think i found my problem guys.

only 1 of 3 fans at my aio ramps up to 100% (from what i hear and feel )

my AIO pump is connected to the AIO pump header. i have 1 Fan of the 3 connected to the CPU fan header, so i dont get the missing cpu fan error when start.
the other 2 fans are connected to the motherboards "fan 1 and fan 2 on the back of the mainboard.
do i need a splitter pwm cable so all 3 fans go into cpu fan header?

I went on longer than I intended to. I'm off work and a little bored, so here's a wall of text for you to read....

To keep things simple, you'd want all three fans plugged into the same fan header. If the AIO doesn't provide a solution of its own, you can get splitter cables to do that. Noctua has a few solutions. IIRC, they have 3-to-1 splitters. You can connect quite a few to a single fan header. I had up to 6 on one for a push/pull setup. Alternately you could just set all three fan headers to ramp up on the same temperature readings. I like to keep things simple, though.

Do keep in mind that some BIOS will allow you to turn off that CPU fan speed monitor. If it's easier to run the fans off of a different header, you could still do that. Some AIOs run fans off the head units, so being able to turn off that monitor is handy to have.

As I said in your other thread, it's not something to really worry about. Going high in an instant isn't as much of a worry as how high the temp is. Hitting 88 is a tad on the high side. Anything in the 90s would be worrisome. But also keep in mind that Cinebench is a stress test, not a real world scenario. Most any other time, your CPU isn't going to be forced to run every core full bore. And if you are running things that would, like video editing, CAD/CAM software, etc, then OCing your CPU wouldn't be recommended. Set EXPO and let the system figure out the rest.

Plastic cover? I'll assume you mean whatever piece of plastic protection came from the manufacturer. Typical mistake is to leave those on. Other than thermal paste, it should be direct metal-to-metal contact. Nothing else should be in-between as it would act as an insulator.

For the pattern, it doesn't make much different. It's been debunked by several reputable YT tech channels. You really can't get the pattern wrong, only the amount. I tend to spread it evenly on both like I'm making a PB&J. I do it mostly for neatness, and when I'm lazy, I just do the 'X'.

And as long as it's a good quality paste, you won't find a lot of deviation from one to the next. Even the old standard Arctic Silver will perform just as well. The only difference these days is how long does the thermal paste take to dry out. That's where the more modern versions stand out. NT-H1/2, MX-4/6, the Thermal Grizzly line. Even the factory paste is decent these days. But use what you're most comfortable with. Just don't get sucked into the rabbit hole of finding the "best paste" unless you're attempting to break OC records. And at that point, you'd probably just stick with liquid metal solutions like Conductonaut Extreme.

Silicon lottery. Not every CPU is the same. I have the same CPU you have and can't hit the same PBO settings. I'm not concerned about it, and neither should you. Performance gains are going to be minimal between one CPU to the other. A lot of people these days get hung up on squeezing every last drop out. It's fine if that's what you want to do. I find it healthier to just get a bit more than stock and spend more time using it.

Always run the pump at 100%. It doesn't take that much more electricity to do it and some AIO pumps can fail early from the constant speed changes. It will inherently keep the CPU/AIO cooler just from that.

As for the fans, I would set them to ramp up on GPU temperature. AIO fans are not cooling the CPU. That's the head and the pump with the water. The fans are cooling the water through radiator. If the case is building up heat because of the GPU, so is the water in the radiator as the fans lazily pull that hot air into it. Better to spin the fans up to help move the hot air out of the case, dropping its temperature.

CPU-temp controlled fans make sense with air-cooled CPU heat sinks. You still have the GPU issue, but then you run the case fans off those GPU temps. Since your AIO is doing double duty as a CPU cooler and a case cooler, you need those fans to act as regular case fans.

But that's my opinion. I've been in debates about this topic with others. YMMV.

Like I said, you're not going to benefit much from a different paste. Stick with what you have.

Case/AIO manufacturers will tell you it's best to front mount an AIO so it is always pulling in cooler air rather than making use of the case's hotter air. So that's an option. I've done both. Although, sometimes because of the case design it's easier to just top mount the AIO. Vertical mounting requires you to be mindful of pump head and radiator alignment to avoid air from occupying the pump head. Some case/AIO combinations just don't allow it.

With my advice on GPU-temp controlled AIO fans, it won't make a lot of difference anyway. The proximity of front fans to the top AIO fans will allow cooler air to enter the AIO quickly in times of need as they ramp up to expel the hot GPU air.

Afterthought: There is no perfect solution. You have to do what's best with what you have. Maybe you have to accept that you can't push your CPU as hard as someone else's. And that's not bad, just different. You could spend the next several weeks/months trying different settings, even swapping out different 7800X3D's searching for the best setup. And I know people that will do that. If that's what you want to do, go for it. I find the more practical approach to be more beneficial.

Again, sorry for the wall of text. Guess I had a need to write all that out.

thanks alot mate!



i did changed the thermal paste , and buyed a splitter for the radiator fans.
nothing changed lol. ok atleast iam safe now that i know its not about the thermal paste.

using noctua nt-h2 now
temps trough cinebench multi is now 86.1c* but i have to say my room temp is 27*c . bit hot in here, but i dont know if the max temp would make a difference when my room temp is 20*c

so, as u said , i think its lottery. or my friends room temp was alot cooler (as i said i dont know if this would make a diff)

all these temps was from HWINFO or my NZXT software

in Ryzen Master i have 10*c less.. than in the other softwares.

i guess iam in the range. and shouldnt be worried about since in gaming my cpu stays at like 60-65*c

again thanks for your time!.

[Tezzious]

with pbo on your temps are fine at 88c when benchmarking via cine bench, my 5800 reaches that too, but i have since disabled pbo, seen no performance loss and idle temps are 23c and maxed out temps are 47c using triple fan rad.
