Hello!
Just made my first gaming build; gtx 1080, i7700k, maximus IX hero, seidon240v, Corsiar vengeance 16gb ram.
Think I put it all together okay tests run okay on it ( no stress testing to nervous) no other real issues apart from the cpu keeps overheating ranging from 39c-42c ideal then goes up to 49c+ when on games got 3 fans going in case.

Any help would be great use this site a lot for info

Clarkeuk,

On behalf of Tom's Moderator Team, welcome aboard!

At the top of all our Forums you'll see "Stickies" which are informative Threads that are permanently "stuck" in place so they're always available as reference material for everyone's benefit. Near the top of the CPU's Forum you'll see this Sticky: Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

You might want to give it a read. Sections Sections 12 and 13 will explain how to properly test your rig using standardized methods which minimize hardware, software and environmental variables. Follow the "Setup" in both Sections to replicate Intel's test conditions. Each 10 minute test will establish a valid thermal "baseline" at steady 100% workload and at dead idle.

Based upon the information you've given, your processor is far from overheating.

Here's the accepted operating range for Core temperature:

85°C Hot
80°C Hot
75°C Warm
70°C Warm
65°C Norm
55°C Norm
45°C Norm
35°C Cool
30°C Cool
25°C Cold

Core temperatures above 85°C aren't recommended.

Core temperatures increase and decrease with Ambient temperature.

Highest Core temperatures occur during stress tests, rendering or transcoding, but are lower during less processor intensive workloads such as applications and gaming. Core temperatures vary greatly between games as CPU workloads differ. Idle temperatures below 25°C are generally due to Ambient temperatures below 22°C.

Once again, welcome aboard!

Just seems really odd tho my rig should be able to handle most games with out causing to much fuss but gaming for 30 mins gets louder, cpu goes up to 60-70c+ just then when I was on explore went to 48c then shot up to 70+ then down again. Could be I messed up the thermal paste? I have the seidon 240v in the CPU fan header that right?

Sorry bout the questions just new to this and spent a lot of money lol cheers again guys

Core temperatures respond instantly to changes in load.

Intel’s specification for Digital Thermal Sensor (DTS) response time is 256 milliseconds, or about 1/4th of a second. Since Windows has dozens of Processes and Services running in the background, it’s normal to see rapid and random Core temperature “spikes” or fluctuations during the first few minutes after startup, which should eventually settle. Any software activity will show some percentage of CPU Utilization in Task Manager, where unnecessary Tray items, Startups, Processes and Services that contribute to excessive or continued spiking can be disabled.

6th Generation processors introduced "Speed Shift" technology in Windows 10, which responds faster to changes in workload than "SpeedStep" due to having many more Core speed and Core voltage levels. Since 7th Generation Speed Shift is twice as fast as 6th Generation, some i7 7700K users complain of severe Core temperature spikes which cause fluctuations in fan RPM at idle. Motherboard manufacturers are currently developing BIOS fixes that include separate SpeedStep and Speed Shift settings with more flexible fan curves and time delay options.

I would certainly not expect 70C temps during gaming...

I only see 70-72C during Prime95 ...such loads are impossible to generate while only gaming....

(For reference, running a Defender quick scan sees 41-58c fluctuations on my 7700K, sitting mostly at 49-52C)

He's referring likely to some more recent news that showed there are quick SPIKES to 90degC or so even if the temperature is showing 75degC.

This is not referring to sustained 90degC. These temperatures show up if you record the MAXIMUM but may not even be seen if just looking at the CURRENT temperature.

Seems changing the seidon240v into the AIO_pump header solved it previously had it in the CPU_fan so changed it over and ignored the CPU FAN in bios seems to be running at 35-45 browsing etc gaming 50-70.
