And even when I am running encoding tasks I barely see my setup hit 70c. I wouldn't run my CPU into the 90s under regular load, even high 80s is stretching it, but like you say, there's a big difference between synthetic and gaming loads, in which I usually get to around 45-55c.

But, when it would come to torturing through Prime95 and Realbench, this processor will not be able to maintain an ideal temperatures.Ĭould motherboard be giving in more voltages despite manual settings?Īlso, One thing I did notice while overclocking i7 4790K is, when I increases the multiplier in BIOS, let's say x45, the Turbo mode under 'CPU Power Management' switched to Enabled. The max temperature reached at 72C, which leads me to believe the processor is actually good at gaming load. On the other hand, I have ran AIDA64 'Stress test', not FPU. Looking at your temperatures, I can say, my i7 4790K's thermal results are not that bad. Secondly, I think TIM is fine as wo different TIM units have been used of same Noctua NT-H1.įYI, I am testing this CPU in an open environment as test bench it rules out any dust/cleaning factor. And, I already had tried dual tower SilverStone Heligon HE01 for comparison, but nothing changed. I don't think Noctua NH-U14S is low for i7 4790K, especially at those clocks. So previous testing and latest testing all are same, as far as the program version goes. I have been using Prim95 25.11v thoughout the testing. Hello, thanks for your detailed and handful of information. It might be wise to compare your VRM output current/power too, as this directly determines the temperatures given all else constant.
Also, might be a chance that the TIM is degrading on your chip. Enough to make me believe the delid and ambient temps can make the difference. I'd guess this is a little cooler than what you are getting, but not by much. They just run hot.Įdit: Just did some testing with p95 25.11 and tuning my OC settings, 4.6/1.245 gives me ~115w power on the VRM output, package temp sits steady at 88c, core temps are 86 on highest and 75 on lowest. I would suggest looking at whether you need to clean the dust out of your system, that may be the culprit, but honestly the power/temp values look like more or less what I'd expect from these chips. Unfortunately the older screenshot doesn't show the power draw or the p95 version, so it's difficult to tell whether the processor is suddenly drawing more power (due to newer p95 version possibly) or is just cooling worse for one reason or another. I do however have the delid (which dropped my temps by around 7-8c and my system (heatsink included) was recently completely cleaned of dust, so the cooling might be slightly better than what you are getting. That would lead me to believe the processor is behaving normally in terms of its power throughput.Īt those power levels I usually have the package temp hovering in the mid 80s and the core temps around 70-75c with one of the cores ~80c, above the others. Power wise you are getting around 90w overclocked, for reference what I get at 4.6/1.25 is around 95-105w using XTU. Ok, same cooler as me, similar voltage/clocks. you may see 4600mhz in cpu-z but the cpu is throttling, temps don't skyrocket as much and performance suffers a lot. power throttling can and will occur even if clocks are reported correctly. Your 4790K 1.26v only reaching 70-ish degrees in p95 on your cooler makes me think it was either power throttling or it was some lighter test in p95. I experienced sth similar in the past and the issue was the thermal paste not spread evenly. game stable is enough, to check the stablility and performance improvement I suggest dropping the games to lower resolution and detail to really stress the cpu and see how much returns the oc actually brings.Īlso, I noticed huge temp amplitude between cores. I haven't touched prime on my last two cpus (4790k,5775c) and they ran rock stable overclocks for over 3 years combined now. My suggestion is simply not to run prime95. Either replace the cooler with a push-pull dual tower or get a 5775c.
