GTX 880M running very hot under load (92C with DX11 burn in)

[Asrah]

I recently purchased a MSI DominatorPro 890. It came with an i7-4810MQ@ 2.7GHZ/3.7GHZ Turbo, and a GTX 880M. My GPU runs at 92C on full load using MSI Kombustor DX11 burn in test at 1080P. Temps arent as bad when running the OpenGL4.4 test at 1080P, hovering around 75C-77C. Both tests are with fans at maximum speed via the G-Panel button, and i have a CM Storm cooling pad propped up on 3 inches of books on the left and right sides.

Im worried that the card might not have as long a life expectancy as desktop cards of the same caliber. I have replaced the thermal paste with Arctic Silver 5. I built both of my desktops myself, so im rather well versed in applying thermal paste properly. I wonder if i should use a different type of thermal paste, or if i should expect the $1000 GPU to fizzle out in a year or less.

Idle temps were about 38-40C for the CPU and GPU on first boot up after i reapplied the thermal paste. After 4 cold boots (one per morning) idle temps are between 50-55C for the CPU and 55-60C for the GPU.

Maxed out the gpu will be consuming 122w of power, that's a lot for the heatsink a they could fit in a laptop.

If you have the fans turned up then there is really no way to reduce tempertures other than downclocking.

Thank you. I reapplied the Arctic 5 Silver again, after cleaning the heatsinks and CPU/GPU caps twice, with 91% isopropyl alcohol. I used the line method, since i dont have any clean cards. The temperatures are about the same. 2000RPM 62C for the GPU, 50C for the CPU. Currently watching a YouTube video with hardware acceleration enabled.

Could you post a picture of the gpu heatsink?

Could you post a picture of the gpu heatsink?

CPU

The 2 parts of the combined piping are the exact same as the 2 parts in my laptop. There is a piece of copper piping that connects the two. Its the same thickness/width/etc as the copper piping on the main heatsink halves. the connecting copper is about 4-5 inches long, if that matters.

I received my SSD in the mail, and put it in the spot where the HGST HDD the laptop came with was. i dont know if that had anything to do with it, but the idle temperature of the CPU and GPU are now 36-38C for the GPU and 39-42C for the CPU. Have not reapplied the thermal paste since before i had the SSD. The temp difference is between one shut down at 55C idle, and a cold boot at 38C idle for the GPU, and 50C/42C for the CPU.

Did the temps lowered down under full load after you replaced your hdd? Or it still around 92 degrees C?

- 16GB Dual Channel DDR3L at 1600MHz (4x4GB)
- NVIDIA® GeForce® GTX 880M graphics with 8GB total GDDR5
- 17.3 inch (439.42 mm) 120Hz WLED FHD (1920 x 1080) TrueLife 400 Nit Display w/3D Bundle

- 5G WiFi Broadcom 4352 802.11n/ac and Bluetooth 4.0
- Slot-Loading Dual Layer Blu-ray Reader (BD-ROM, DVD±RW, CD-RW)

My temp while running FurMark and Prime95 together are GPU 94C and CPU below 85 even after repasting with ArticSilver 5 Looks like this is a manufacturing fault by Nvidea or many be these cards are meant to stay this Hot.
