i7-3770K Max Temp?

[prince_xaine]

Mainboard: OptiPlex 7010
CPU: i7-3770K
GPU 1: GTX 1080 Ti
GPU 2: Radeon HD 7750
RAM: 32 GB Corsair Vengeance
SSD: Samsung 850 Evo
HDD 1: WD Black 6TB 7200 RPM
HDD 2: ST500DM002-1BD142
PSU: ATX 1050W 70+ Certified

It's all there just in case. Anyways, how hot should my CPU get? At 100% load it tops off at about 80 degrees Celsius, and idles between 50-60. It is air cooled.

Keep it under 90 and I think thermal throttle starts at 100.

Dont know what air cooler you have so I have no idea if thats high or low.

AT 80C you are fine just keep an eye on it you don't really want it going higher than that as performance will really decline and it's not healthy for life of CPU

prince_xaine,

Throttle temperature for the i7 3770K is 105°C, which of course, is too hot.

Among Intel processors, the highest Tj Max Throttle temperature is your 3rd Generation Ivy Bridge at 105°C (221°F). Although most processors Throttle at 100°C (212°F), some variants Throttle at lower Core temperatures. Nevertheless, it’s not advisable to run your CPU near it's thermal limit, just as common sense tells you not to run a vehicle with the temperature gauge pegged in the red "hot" zone.

If your hottest Core is near it's specified Tj Max Throttle temperature, then your CPU is already too hot. The consensus among well informed and highly experienced system builders, overclockers and reviewers, is that cooler is better for ultimate stability, performance and longevity. Experts all agree that it's prudent to observe a reasonable thermal margin below Tj Max. So regardless of environmental conditions, hardware configurations, workloads or any other variables, Core temperatures above 85°C are not recommended.

Here's the operating range for Core temperature:

Core temperatures below 80°C are preferred.

Core temperatures increase and decrease with Ambient temperature.

Your idle temperatures are very high, so is "idle" really "idle" at just 1 or 2% CPU Usage in Windows Task Manager?

What is your Ambient temperature?

Room Temperature: 22C
Temperatures :40C Min; 77C Max | The CPU is NOT overclocked.
Air Cooler: Dell 89R8J

Thanks for the responses.
I just want to be sure that I don't need a better cooler for it.

I have the non K i7 3770. I have noticed that the cpu drops all core turbo boost frequency when any core hits 78C. So i had a cooling solution to keep it below 75C.

With room ambient of 22, with good airflow in the case your idle temps should be @6-12°C higher depending on fan curves.

If you are seeing 40°+ idle temps, that's high. Either the fan curve is off slightly and cooler fans are not running sufficient rpm, the cooler is dirty or more likely you have pretty lousy airflow.

My i7-3770K in 22°C ambient runs @32° idle and 74°C under Prime95 v26.6 at 1.32v @4.9GHz in a Fractal Design Define R5 with the door closed, 2x 140mm top exhaust and 280mm AIO as intake, fan rpms don't exceed 900.

You need airflow, balanced between intake and exhaust, get the heat out of the case, replaced with cool air from the room, temps will drop.

If airflow is the problem, which likely it is, I would need a fan that fits the OptiPlex 7010 MT:

It is large enough to fit a full size PCI-e slot card in. I've never replaced a CPU cooler before, so I don't know what to get. Maybe I should just turn my fan to max speed? (I can't adjust otherwise. BIOS allows auto or MAX on CPU fan)

 

[Karadjgne]

You got all that in that tiny case? I'm impressed.

OK, yes, airflow is definitely a problem there. Since you upgraded the psu, that fan should be pointed down, this and the exhaust fan underneath are going to be the main sources of airflow. Your only option for intake is make something like a Good 120mm fit above the HDD rack somehow. The more air it helps suck through that obstructive front, the better. I'd suggest the quietest fan you can get as it'll need to be running high rpm just to create enough vacuum.

You can use SpeedFan (if you can figure out how to use it, it's a pain) to control speeds of any fan in the pc, according to curves you set up, so you aren't limited to auto or max for anything.

 

[prince_xaine]

I would love to add an intake fan, but my motherboard only has a slot for 2 fans; the CPU fan and the Exhaust fan. Also, the front of the case is very breathable. You can feel a lot of the air from the fans on the 2 GPU, CPU fan, and PSU fan come through. It also has a dust filter on the front behind the external chassis, so it is a very well built Mini-Tower. I tried pointing the CPU fan down once, and I had issues so I had to turn it back around. I think it was because the fan doesn't operate at different levels? I'm thinking it only operates at low or high speeds.

EDIT: After turning my fan control override in BIOS to on, and the fan running at max speed, these are my new temps:
Minimum: 35C
Maximum: 68C (Under 100% load for 5 minutes)

I also ran a quick benchmark:

Note: I don't like the idea of my CPU fan running at max speed at all times. Not only is it very loud, but it will definitely wear quicker than if I leave it be. It also turns out I cannot control my CPU fan with software, as I only have 3-pin fan connection for my CPU fan, and I cannot control the amount of voltage supplied to the motherboard.

So I suppose it's either normal or max speed for CPU fan?

Mine runs below 60c even at 100% usage with just a Hyper 212 evo (fan stays below 600). But that's also with a large "performance" case.

You can add fans and just attach them to the power supply, you don't need to connect them to the motherboard. Some fans will have switches or knobs where you can adjust the speeds too, along with fan software like suggested above.

 

[Karadjgne]

I'd use a 2way splitter. Hook the front intake fan and the rear exhaust fan to the same header. I'd also not use any eco mode setting on the psu, let the fan run. Heat will naturally rise, and any and all higher fans will create a vacuum or lower pressure area at them. Air will move to fill that void, which is why you feel the breeze at the front. However. At low fan speeds, there's not much vacuum, so air is not drawn into the case very much, which means the case doesn't exhaust very much either, heat collects and sits, so the cpu fan is pretty much recycling warmer air at idle, temps go up. The addition of a front intake puts its vacuum directly on a cool air source, so even at slower speeds, it's exhausting cool air into the case, cpu idle temps go down.

You need flow. That means air pushed in, air pushed out. Relying on just the suction created by high speed exhaust means at low speeds, there's little suction at the front, as there's more available air to be found by the gpu bracket and other cracks near the strongest pull from the fan.
