Intel Core i7-5960X 8-Core Haswell-E Processor Review

Intel Core i7-5960X CPU Temperature Testing


The Intel Core i7-5960X Processor DOES NOT use Next-Generation Polymer Thermal Interface Material (NGPTIM) like the Core i7-4790K Devil’s Canyon processor uses, but we were still interested in seeing how hot the chip gets. We took a look at idle and load temperatures on the processor with Gelid Extreme Thermal Compound on the Corsair H105 Closed Loop Water Cooler. We used the Intel Extreme Tuning Utility v5.1.0.23 to monitor the temperatures.


At idle we found the Intel Core i7-5960X processor to be at 32C with a CPU core voltage of 0.7400V.


When running Handbrake we saw the temperature jump up to 50-52C with a CPU core voltage of 1.0190V.  The processor wasn’t pegged at 100% load though with Handbrake as the CPU Total TDP for the 5960X was just 105W.


With Prime95 64-bit we were able to get the CPU Total TDP up to 140 Watts and the processor was pegged at 100% use at 3.3GHz.  The temperature seemed to settle down at 62C with 1.01V, which isn’t that bad if this utility is reading the Core i7-5960X Haswell-E CPU temperatures properly.


So, on our system with the Corsair H105 water cooler along with Gelid Extreme Thermal Compound we were running around 32C at idle and hit 62C at load. Not bad temperatures for a true 8-core processor, but keep in mind the clock speeds are relatively low as is the core voltage. The Intel Core i7-5960X actually has slightly lower load temperatures than the Intel Core i7-4790K and the Core i7-4770K, which some people might find interesting. The 5960X might have more cores, but they run slower with less Voltage!

  • Price of DDR4 is bad I bought 32 GB will wait on the other half .

  • I ordered a i7 5930k for my Haswell-E Build, hopefully it arrives by this weekend but for me I just cant justify the cost of the 5960X. 2011-V3 socket will have plenty of new chips coming out during its life span so I expect to see 8-core chips fall to the $400 range in the next year or two. I’m happy with my 2500k but just have the itch to upgrade and would like to to run crossfire 290s now that they can be had for $250 and my current motherboard is PCI-E 2.0 and will run then 8x 8x, plus I could use the extra encoding speed of the new Haswell-E chip. Anyways I’m excited!! great review as always!

      Sorry pal, I’m from the future and I have to tell you, your assumption is wrong. Looking at the price of the i7 6900k Octa-Core makes me laugh when I read your comment. Its about 1,100$ right now. I don’t think Octa-Cores will drop below anywhere near 400$ or 500$ within the next 5-6 years.

    Do you know if PSU Corsair AX850 can handle 5960X at 4.4-4.6Ghz?

    • yeah, it sure can

    • A friend had one overclocked at 4.4GHz with a 780ti overclocked to I think 1120mhz, and he was drawing about 550 watts at full load.

    Next year Q4 the regular Chips will be out and run DDR4 on new M.B, by then the Ram should come down in Price. No time date only rumor that a 3.5 6 core for 350$ will be the high end. I’ll wait.

    You’ve got remnants from G3258 pages in the Overclocking section and likely elsewhere, but that’s the only page I read.
