AMD 2400G Stock Temps

Just installed a new 2400G and its a tad hotter than what i was expecting.

Previously i had a 3570k (stock) in the exact same case with the exact same cooler and i was getting temps around 65 degrees.

With the 2400g at stock in the exact same case/cooler I'm getting 85 degrees.

Are these just very hot chips? It only seems to really ramp up the temps when running heavy CPU loads. GPU loads seem to top out the temp at 65ish.

Just wondering if its worth reseating or if its normal i will just de clock it to get it around 65-70 degrees.

Thanks,
 
What board do you have, and what cooler? That does seem high to me, did a 2200g build for a mate and full load on CPU and GPU topped out at 70 with a mild OC
 
MSI B350M Mortar board, Silverstone TJ08-E case, Thermalright HR02 Cooler.

Slight strange fan arrangement, i mount a 140mm fan in the front of the case which is only 20cm away from the heatsink so I've never bothered with the CPU cooler fan. Worked well for the 3570k for the last 5 years.

I was expecting temps around the same as the 3570k as the TDP is not miles apart (65 vs 77watts).
 
If you're using the exact same cooler then I'd suggest checking you've installed the AM4 mounting correctly and you've properly seated the cooler on the board.
 
I will have ago at remounting it with some new TIM. I bought the updated AM4 mounting kit from thermalright so it should fit correctly.

Looked that case up, apparently it comes with a 180mm fan which you've changed to a 140mm fan.

But you have that fan behind a hard drive cage and it's the only airflow for your CPU cooler which is even further away?

Whatever else you try I'd suggest putting a fan on your cooler. It's extremely inefficient to have that much space (and the HDD cage?) in the way. There should be a massive drop in temps just from putting a fan on even at low speeds.
 
Should clarify I've removed everything (HDD cage etc) and i have serious OCD about cables. I also use a lot of acoustic foam to pad the interior of the case to further improve airflow from front to back. The fan i currently use is a Corsair ML140 as the Silverstone 180mm fan is very noisy. I will try with a separate 140mm fan on the heatsink itself its just a shame as I've had the 3570k in the exact same conditions for years doing extended times encoding and always kept below 70c.


Idle temps sit around 36 degrees with the fan at 400RPM it just seems a bit strange that when under load the CPU has such a massive temp delta.
 
You shouldn't see volts go above 1.32 even under boost for the CPU core. I think normal volts are closer to 1.2 but they vary depending on the bin of the chip I believe?
 
I have a 2400G at stock.

Prime95 small FFTs, vcore fluctuates between 1.344v and 1.360v.

On something less intensive like the cpu-z stress test it is locked at at 1.360v.

Runs at a 36.3x or 36.5x multiplier and peaks at 61C under prime95. My cooler is a noctua nh-u14s though.

With ambient of 22C, idle temps are 29C-33C.

In terms of thermal performance this is worse (given it is only 4 cores) than other soldered Ryzen chips I have owned. 1.360v is generally enough for Ryzen 1xxx chips to do 3.7-3.9 in my experience and something like 1600x doesn't run much warmer than 61C (prime95) with the same cooler.

Been testing yesterday and managed to work out at least some of the problem. The motherboard with boost on gives the CPU in the region of 1.36 to achieve 3.9ghz default boost. If I disable boost and leave on auto voltage at 3.6ghz it gives the cpu approximately 1.25v which gives max load temps of 62 degrees and which is far more acceptable for my usage.

The only frustration I have at the moment is no matter what I do in the bios the motherboard keeps the voltage on auto. Not sure if anyone has any experience with MSI motherboards, but is there an option I need to enable to stick to manual voltage?

I only had the stock cooler on for a day and feel reluctant to change it all back over.

Is thermal grizzly much better than arctic silver 5?

Just for reference a fan 20cm away will give almost no airflow through a good air cooler as it'll not give any static pressure (unless there is some containment/casing forcing the airflow through it?). I'm surprised the 3570k didn't give you issues tbh.

The HR-02 is designed to be used as the OP is using it with no attached fan but some airflow going through the fins from a nearby fan. Having said that cooling will not be as effective as having a fan directly attached. I believe that I read / heard somewhere that the way TDP is measured is not the same between manufacturers so even though the quoted TDP of the new AMD chip is less than the TDP of the old Intel chip it's still possible that the AMD chip runs hotter and so the cooler without a fan is no longer adequate.

I would agree that as long as it has been properly applied the type of paste used is not going to make a significant difference, certainly not the 20c difference the OP is experiencing.

/Edit: The HR-02 is a great cooler (I have one) and rivalled the Noctua NH-D14 in reviews though this was with fan(s) fitted.
 
If the HS is designed for it then fair enough, most would not perform well in this scenario as you get better cooling performance with greater fin density, but that requires increased static pressure to get any airflow through it. Not looked at the HS in question tho *shrug*
