i7-8750H Cores Heating Uneven

Hi,

 

I have an MSI GS65 "Stealth Thin" laptop with an i7-8750H (6 cores). When running benchmarking workloads, I notice that a few of the cores heat up unevenly.

 

Does this possibly indicate a need to remove and re-paste the CPU heat sink? Or could it be due to something else worth looking into?

 

Thanks.

 

Running Prime95 small FTTs:

Core 0 ... 79C ... -1C from core 2

Core 1 ... 75C ... -5C from core 2

Core 2 ... 80C ... taking this core as baseline

Core 3 ... 75C ... -5C from core 2

Core 4 ... 79C ... -1C from core 2

Core 5 ... 74C ... -6C from core 2

That is kinda normal. At least my r7 3700x does the same thing

Tier lists for building a PC.

 

Motherboard tier list. Tier A for overclocking 5950x. Tier B for overclocking 5900x, Tier C for overclocking 5800X. Tier D for overclocking 5600X. Tier F for 4/6 core Cpus at stock. Tier E avoid.

(Also case airflow matter or if you are using Downcraft air cooler)

Spoiler

 

Gpu tier list. Rtx 3000 and RX 6000 not included since not so many reviews. Tier S for Water cooling. Tier A and B for overcloking. Tier C stock and Tier D avoid.

( You can overclock Tier C just fine, but it can get very loud, that is why it is not recommended for overclocking, same with tier D)

Spoiler

 

Psu tier List. Tier A for Rtx 3000, Vega and RX 6000. Tier B For anything else. Tier C cheap/IGPU. Tier D and E avoid.

(RTX 3000/ RX 6000 Might run just fine with higher wattage tier B unit, Rtx 3070 runs fine with tier B units)

Spoiler

 

Cpu cooler tier list. Tier 1&2 for power hungry Cpus with Overclock. Tier 3&4 for overclocking Ryzen 3,5,7 or lower power Intel Cpus. Tier 5 for overclocking low end Cpus or 4/6 core Ryzen. Tier 6&7 for stock. Tier 8&9 Ryzen stock cooler performance. Do not waste your money!

Spoiler

 

Storage tier List. Tier A for Moving files/  OS. Tier B for OS/Games. Tier C for games. Tier D budget Pcs. Tier E if on sale not the worst but not good.

(With a grain of salt, I use tier C for OS myself)

Spoiler

 

Case Tier List. Work In Progress. Most Phanteks airflow series cases already done!

Ask me anything :)

Can confirm this is normal but from a 2500k instead. You could replace the thermal paste from factory to get lower temperatures across all cores, it will also give you an opportunity to remount the cooler for your laptop but in all honesty you have nothing to worry about, especially if those are the temps you are getting after running P95 small FFTs, you should be fine.

My PC specs; Processor: Intel i5 2500K @4.6GHz, Graphics card: Sapphire AMD R9 Nano 4GB DD Overclocked @1050MHz Core and 550 MHz Memory. Hard Drives: 500GB Seagate Barracuda 7200 RPM, 2TB Western Digital Green Drive, Motherboard: Asus P8Z77-V , Power Supply: OCZ ZS series 750W 80+ Bronze certified, Case: NZXT S340, Memory: Corsair Vengance series Ram, Dual Channel kit @ 1866 Mhz, 10-11-10-30 Timings, 4x4 GB DIMMs. Cooler: CoolerMaster Seidon 240V
