GTX1080 Thermal Throttling

[joncla]

I've had my laptop for 10 months now and it's always run a little on the warm side. I undervolted the CPU and this has kept the CPU temps under control (i7 8700K), but during all my temp monitoring I've noticed that my GTX1080 is thermal throttling (using GPU-Z to monitor temps and reason for throttling).

Now I've gone through the process of removing the old thermal paste and putting new which has brought the CPU down a few degrees and appears to have slowed the GPU heating down, but it still hits 90c and then thermal throttles.

I'm trying to decide the best approach. I know people have had mixed success with RMA'ing their laptops and CLEVO "repairing" the GPUs, but I'm wondering whether to try a small undervolt first to see if I can get temps under control (I'm fully aware that cramming desktop components into a laptop chassis is always going to cause some headaches). I know by undervolting, I'm probably going to reduce the speed of the card ever so slightly, but it would be a good compromise to keep GPU temps in the 80c's range.

Am I complicating matters and should I just ask PCS to look at it?

The GPU's not a desktop component, it's a mobile one. Granted more powerful than many desktop GPUs, but still, 90 degrees isn't okay (I'm assuming under real-world usage and not hammering it with Furmark or something?)

GTX 1080 Octane users haven't generally reported problematic GPU temps. 90 degrees seems exceptional, and you should treat it as a fault rather than just downclocking, costing you performance, to 'fix' the problem. Because it's not fixing it.

If it's a PC Specialist system, contact them to report the fault and set out the troubleshooting you've already attempted.

If the laptop's 10 months old then it's under warranty for parts and you want to get this logged while that still applies.

Kind of a dumb question, but what is the base temperature where you are at? I usually notice a performance drop (like 5-10% averaged) between winter and summer (we are talking going from 10-15C to 30-45C). It may be something which is not picked up by PCS as they are UK based and likely test in a semi-controlled environment.
I have the previous iteration of that system and I´ve hit high 80s in those summer conditions.
