i7 4790k temps okay?
Hello
I've optimized my 4790k to 4.7ghz and executed prime95 for roughly 7 minutes.
Using a noctua dh15, the readings in HWMonitor were around 61-63°C, then a sudden spike reached nearly 80°C before I halted the test and it returned to 28-30°C at idle.
(Just did another 5-minute run and stayed in the low to mid 60s range)
Are these temperatures acceptable? Thanks.
I had a really bad bad run of luck w/ Asus Z87 boards and since then we have been using MSI and Giga ... Z170 reviews and user ratings are up substantially over Z97 so we may give Asus a try again with some upcoming Z170 builds. What I am getting at is, we never did get around to doing a script for our Asus Z97 users to OC their boxes. We'd show them how to get sat 42 multi and let them take home and do from there. But here's the Z87 Asus script.... easily adaptable for Z97. Of course, w/ 4790k, you'd start at 45 or 46 CPU multi

They perform well and it's important to remember that stress testing tools like Prime95 and others will generate higher temperatures than what you experience during actual gaming or real-world use. Therefore, even with a mid-60s rating in P95, you'll likely see high scores in games.
60-69 is great
70-79 is okay
80-89 is warm
90-99 is hot
Target the 60-75 range for best results. 80 isn't the best choice.
Slurpee12:
Temperatures between 60-69 are excellent.
70-79 are acceptable.
80-89 feel warm.
90-99 are hot.
For best results, target the 60-75 range. 80 is not ideal.
I plan to conduct another test tomorrow to confirm it isn't actually reaching 80, as the previous test stayed under 65.
OK for what? Which P95?... the previous one without AVX or other advanced instruction sets of the newer ones? P95 actually doesn't reveal much except whether your cooling system can maintain it, because it will display significantly higher temperatures than your machine can ever reach. With today's modern instruction sets and auto-adjusting voltages, P95 becomes quite confusing. The older version won't trigger those intense voltage changes, but those changes are actually due to the instruction sets used by contemporary programs. So if you've been stable for 4 hours using the old version (26.6), all you're really showing is that your CPU remains stable and not excessively hot—except when it runs any program with modern instruction sets. Question is, did you assemble your PC to handle P95 or just to run applications? I suggest you check out these links: http://rog.asus.com/forum/showthread.php...load-Links http://www.hwinfo.com/download.php Instead of copying, I’ll point you to this post: As mentioned, I’ve found myself stable at 80+C and failing in RoG RB at 70C, so I don’t bother using P95 except for thermal cycling to test TIM. In the 90s, you start seeing throttling once you reach 85°C for extended periods, and degradation is likely happening.

You want to aim for 60-75 range for optimal temps. 80 isn't ideal.
I will run another test tomorrow just to make sure it isnt actually hitting 80 since the second test didnt go over 65.
Okay, sounds good. I'm running an i7 3820 @ 4.2GHz with Corsair H80i GT and my temps peaked at 65 on Prime95. While gaming, the maximum temp I have yet to see is 54 degrees. If your temps are at 61-63 in Prime, then your cooling is perfect.

What are you asking about? Which P95? The old one without AVX or other new features? P95 doesn't really give much information except whether your cooling can handle it and if it does a bad job, showing much higher temperatures than your machine can actually reach. With today's modern instruction sets and auto-adjusting voltages, P95 becomes quite confusing. The old version won't trigger those extreme voltage changes, but those changes are actually due to the instruction sets used by modern programs. So if you've been getting stable 4-hour P95 runs with the older version (26.6), it just means your CPU is stable and not overheating too much—except when you run any program that uses modern instructions.
The question is, were you building your PC for P95 performance or just to run regular applications?

I think the latest P95 version kept the voltage at 1.350, but it should work for running programs.
If it had remained active, two possibilities existed:
1. The version wasn’t the newest—after the 26.6 update, new instruction sets began being introduced.
2. The voltage was fixed and the power-saving options were disabled.
MoBo makers add features to the CPU’s control system so it receives more power when required. Check the BIOS for terms such as LLC and adaptive voltage control. Adaptive control adjusts the voltage automatically when you power on the PC, rising to around 4.7 but then gradually decreasing to 0.8 until active.
Setting a fixed voltage permanently locks you into that level and 4.7 GHz continuously—this is not advised.
Test it using RoG Real Bench and HWiNFO64.
In Real Bench, adjust the window position to the left side of the screen. In HWiNFO64, run “sensors only” and be ready for a prompt about disabling the Asus EC chip or similar settings specific to your model; click “Disable this sensor.”
Move the HWiNFO64 window to the upper right corner, stretch its bottom to fill the screen, and make these changes:
- Right-click on “System” at the top and hide it.
- Hide the last four lines starting with “Core CPU Thermal Throttling” (irrelevant if you monitor temperatures).
- Skip the following section and hide the part about CPU package through DRAM power.
- Now everything should be visible simultaneously, allowing you to view Vcore 0, 1, and 2 at the bottom of the window. If needed, hide a few more lines. Save and Quit preserves your changes.
If you monitor the four core temperatures and assume adaptive control is active with voltage adjustment enabled, the readings will fluctuate. I usually wait until the CPU reaches about 0.800 GHz before starting—this can take a few minutes.
Here’s what I observed for voltage peaks (lowest to highest core) during each phase of my 4770k (4.5 GHz CPU / 4.2 GHz cache) test in the standard BIOS profile. It’s unclear which test uses AVX.

This is 4.6 / 4.6 – just a test to see how the system reacts with high cache multiplier… usually I set cache to CPU -3 (46/43).
