Is my PC running too hot?

[uberhaxx]

Hello!

 

So I built my PC early 2017 so everything in it are approx 5 years old except for the GPU and M2 SSD.

 

Last night I was playing CoD Cold War on Ultra settings with 65-75 FPS, I guess that's fine, IDK what to expect from the 3070, but it was fluent FPS. However, when I tried to play today, the fps hovered around 40-45 FPS, very laggy, and my computer seems to be running hot since it was very loud and the fans started to spin real hard.

I downloaded Speccy while playing to see my CPU temperature, and it was at lowest 80 degrees celsius and at most 90. Is this normal? It SOUNDS like it is overheating. Shouldn't the liquid cooler that I specifically have for the CPU drastically lower the heat? So, for the PC to run my GPU, do I need to upgrade the CPU, motherboard and watercooler too?? Or is something else wrong?

 

Thanks for any help!

 

My specs are the following:

Watercooler: Corsair Hydro 100x

Processor: Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz

Graphics card: Nvidia GeForce RTX 3070 8 GB

Motherboard: Gigabyte Technology Z270-Gaming K3

Harddrive: 1 TB Samsung M2 SSD 980

Harddrive: 250 GB Samsung SSD 850 EVO

Harddrive: 1 TB Western Digital WDC SATA

Ram: 16 GB DDR4 Corsair Vengeance

PCU: 650 Watt Corsair Gaming

I also use the H100x in my PC. It's alright and should certainly be able to cool a 7700K - especially when not overclocked. 

 

What case do you have? How many fans do you have? How are fans mounted in the case?

Poor airflow could suffocate the AIO. The 3070 also outputs a lot of heat.

90C is rather hot, but it's not hot enough to thermal throttle

 

the 7700K is also a fair enough CPU, and ofc the 3070 is a quite capable GPU, try to find your RAM specs (speed/latency)

[YoungBlade]

How long has it been since you re-pasted and remounted the CPU cooler? 5 years is around the time paste can start to dry out.

 

Have you confirmed that the pump is running for the AIO? If it failed, your CPU will be dramatically hotter. 5 years is also around the time that an AIO can start to fail.

Idk if these userbenchmarks tell you anything? But seems like poor performance of the RAM? Is this reliable?

I haven't reapplied since 2017 if I recall correctly. How do I double check if the AiO is running correctly?

The case is a Phanteks Enthoo Evolve and the 2 fans of the AIO are placed above the GPU, spinning to the CPU. Other than this, theres only one big fan and it spins from the other side to the CPU. So the winds should 'collide' over the CPU

There are two ways to check: via software and directly checking it.

 

Using a program like HWInfo64, you can see what the system is reporting for the pump speed. If the pump speed is 0 rpm or some really weird number (like less than 100 or more than 5000, which is well outside the typical range for an AIO pump) then there's a good chance something is broken.

 

If that data seems normal, or you just want to be sure, you can open up the PC and hold the tubes in your hand to see if you can feel the water flowing. Do note that all the usual safety warnings apply here: sticking your hand in a running computer can be potentially dangerous to you and your components. While generally safe, there is always a risk when dealing with live electricity.

looks to be 16gb of DDR4 2400 CL14, which is all we really wanted from that

 

I might guess the RAM to be the problem, not the CPU

The XMP is not enabled, too. Notice that it says it's running at 2133

I know not to 100% trust userbenchmark, but it even claims it's performing "way below expected"

[Tan3l6]

Userbenchmark is not as useless as people tend to think ...

Seems to be working?

Hmm, from what I'm getting from pictures on Google, it looks like Airflow is pretty bad in that case. 

I also see from the above comments, that you haven't reapplied thermal paste since 2017. 

I think the high temps you see a mixture of the two reasons above, and also because you have added a 3070, which always outputs more heat, than most GPUs would have done in 2017 + a 3070 will pull ALL available performance from the 7700K, so the 7700K will also work very hard in games. 

When you have high temps, opening the side panel, does that drop the temps?

So it might be that the paste has started to dry out.

 

Also, did you enable XMP? What speed and timings is your RAM running at?

Okay.. The temperature doesn't drop if opening the case. But adding new paste sounds like a good idea, just hope it helps

Dried out paste could easily be the issue. Reapply of good new thermal paste can help drastically if this is the issue. Certainly worth trying.

So I went into BIOS and changed the XMP from disabled to profile 1, I assume this is correct? 

 

Also this are the speeds that resulted

[YoungBlade]

That's correct now. That should give you a slight performance bump, especially since the latency is better now.

could be the issue for temps, but it's not thermal throttling, so it can't be the cause of the performance drop

Yeah true maybe. I only really focused on the temps

So your suggestion is to replace RAM or even like the motherboard and CPU?

XMP should help at LEAST a bit, maybe by ~12.5%

Okay so I bought termal paste and reapplied it, no temperature drop at all. Still laggy in games. 

 

Here are my allocations in processes tab, are they weird? Seems weird that GPU is so low and RAM and CPU so high, no?
