3770k high temp

[OCNewbee]

My specs.

CPU: 3770k (no OC)

CPU Cooler: Noctua L9i

Mobo: Zotac z77 itx a-e

Ram: Samsung 4gb 1333 (x2)

Case: Bit Fenix Prodigy

 

Problem: under prime 95 small fft, it hits almost 90celcius. I get nervous and I turn it off at 89 (I set the CPU fan on 100%). I wanted to overclock but forget overclocking, I just want the temps in the 70C~ range.

FYI Ambient temp 26C.

Prime95 is maximum stress, maximum heat. You likely wont see that on everyday usage. With that cooler, you can probably get a mild OC, but dont expect to reach max potential in a small Form Factor, and honestly in Small Form, probably best to not OC due to air flow constraints unless you can somehow get an AIO on it.

new thermal paste?

[Ansuex]

You do not really have the best cooler on the market.

Upgrading the CPU cooler will definitely help

[OCNewbee]

wow such fast responses! thank you all. 

I guess air flow is an issue. Or perhaps I seated the cooler wrong.

As an interesting experiment, I reversed the fan on the CPU. In its original config, it spewed the hot air from bottom to top. I reversed it so that the fan blew wind downwards on to the heatsink. No difference at all  In fact, it was slight hotter by about 2 celcius. The temp went all the way up to 92. Initially I purchased the L9i in hopes of overclocking. My previous cooler on this system was thermolab baram 2010. This cooler kept it under 90. So I think I will be switching back to the original config. What AIO cooler do you guys recommend for bit fenix prodigy?

 

***update***

I cleaned and reseated the thermolab Baram 2010, moved the front intake fans of the bit fenix prodigy case to the top side for a better air flow, and now the max temp is at 76 celicus under full load. I think I can finally begin overclocking.

Yeah, flipping the fan is worse. These fan and heatsink designs favor push over pull.

The Thermolab Baram 2010 is a much larger heatsink that easily performs better. 

 

What's your core voltage set to?

[OCNewbee]

I successfully overclocked the 3770k at 4.4ghz on 1.20voltage. According to HW monitor, my package CPU temp is 84 max while the core temps is around 70~78. Is this too high?

Those temps are fine. 

[OCNewbee]

Which one should I be concerned about? The package CPU temp or core temps?

Package temp is lower than core temps. 80-90c is fine for core temps with a synthetic load.

package temp is higher than core temp. My package temp is in the mid 80s while my core temps are mid70s. Once again, thanks for the quick responses!

That shouldn't be the case since the package temp is of the IHS which is the intermediate temp between the cores and your cooler. What are you using to read temps? It's normal for sensors to be a bit off.

I am using CPUID HWMonitor

Ran mine with a stock cooler, mid, high 80's at 4.5 1.25v. But that was real world being maxed out on bf1.

yeah for me that would be too insane. high 80s during gaming would mean that during prime 95, it would most likely just shut down. I always run prime 95 and use that temp as an indicator. On games, my temps are slightly below 70C on all four cores.

On a different note, after looking at data from msi afterburner, it seems that my 1060GTX 6gb is the bottleneck; at least when I play hitman. To be more specific, the GPU usage is 99% while the CPU is usually at 50~60%. I also OCed my 1060 to 1950 core/2100 memory. This is now sitting at 77C. 

Just ordered a 200mm intake fan for my bit fenix prodigy.(horrible cable management btw...=..( ) With all this OCing, I think I need increase some airflow.

Thanks for all the help. I decided to sell the noctua l9i and stick with thermolab baram 2010.

This would be a 77 watt TDP CPU.

And this is...

The NH-L9i is a highly-compact low-profile quiet cooler designed for use in small form factor cases and HTPC environments. While it provides first rate performance in its class, it is not suitable for overclocking and should be used with care on CPUs with more than 65W TDP (Thermal Design Power).

 

Going by the TDP guideline's sheet they have, for the i7 3770K they specify this:

Recommended with good case ventilation and Intel Turbo Mode disabled only.

 

I think I found the problem.
