System Throttling
Running Prime95 and FurMark at the same time places a very high load on any system, with both the CPU and GPU drawing maximum power while also generating maximum heat. The Panther 5D's CPU is rated for up to 150 W and the each of the GPUs are at least 100 W. Add in 25-50 W for the desktop platform components and you're looking at 400 W or more. Obviously, that's significantly more power than most notebooks draw, and the reason why Eurocom needs to offer dual power adapters. If the system can't get more than 400 W from its supplies, or isn't able to dissipate that amount of heat efficiently, it will throttle the CPU, GPU, or both in order to honor its thermal and electrical specifications.
Synthetic Heat Run
In order to really push the Panther 5D to its limits, we fully load its Core i7-3970X CPU and both GeForce GTX 680M GPUs. The goal is to tax the machine until its internal and external temperatures plateau. The only reason to end a run early is a hardware failure.

In the chart above, you can see the load and temperatures for the CPU and both GPUs.
The CPU took 12 minutes to heat up both of its big copper sinks enough that the fans were spinning at their highest rotational speeds. You can see the slight dip between the 12- and 14-minute mark where the amount of air being drawn in momentarily pulled temps down a bit.
At the 60-minute mark, I shut down FurMark to alleviate the GPU load, dropping them to idle. The CPU temps were unaffected. It was not until I also shut down Prime95 at 65 minutes that the thermals started to relax.
The two CPU fans are on the right half of the computer. When they both kick in, the amount of air they move is startling the first time you feel it.
After close to 20 minutes, the CPU hit 90 °C and throttled down to 3.4 GHz. It stayed at that clock rate for most of the remaining run.

You can see the CPU's clock rate through our run in the chart above.
The first GPU is located next to the GPU, and it sits in the middle of the machine. Its air intake is third from the left. Cooling that graphics processor is naturally a little more difficult, so its temperatures were a few degrees higher than the second GPU, situated all the way to the right.
With that said, neither GPU ran particularly hot during our test, even though they were both fully-loaded for an hour. In the 70-minute graph, you can see a slight dip in their temperatures, which was caused by lifting the machine to measure heat on the desktop under it.

Both GPUs maintained their minimum clock rate during testing.
We saw power drawn from the wall peak at 464 W. Allowing for 10% losses at the power adapters, this means that the Panther 5D was dissipating more than 400 W. Even the power adapters themselves heat up quite a bit. It's naturally important to keep everything around Eurocom's machine well-ventilated if it's under a demanding load.
Then again, we didn't see temperatures spike so high in any real-world workload we through at the Panther 5D.

the main people i can see needing this bad boy is division commanders on a battlefield as well as NSA hackers and CIA spies and Drone operators
but what i really wanted to see was the effects of ocing the gtx 680Ms
Finally I can have high end desktop performance on the go.
Lets see, a SFF setup parts:
PC: 5 = SFF-PC, keyboard, mouse, monitor, 2 power cords.
5D: 7 = 5D Panther, Mouse, 2 power cords, 3 power bricks/converter.
In return, you get a much better keyboard... then when broken, its a $10~150 replacement...
Nice machine, but it is overbuilt for a laptop if you need external monitors to use its full graphics. Sure you can take it somewhere where you can hook it up to multiple monitors, but then it is no more portable than a desktop.
Anyways, nice review. It's fun to read about the stupidly high end laptops that most of us don't ever see or use in real life, just to know what's possible if you go for performance over form factor.
I understand that it's "PERFORMANCE AT THE COST OF EVERYTHING ELSE" but wow.
To put this into perspective for that $6600, you could buy a fully loaded Precision M3800 quad core i7, 3200x1800 IGZO screen, 16gb ram, 512gb SSD + 1tb HDD and a Quadro k1100m that weighs 4lbs for $2600 and still have $4k left over to build a MONSTER workstation/gaming desktop
Lets go nuts. A 4k UP2414Q Ultrasharp Monitor for $1400
Core i7 4770k $300
2 x Nvidia GTX 780ti $700 each
512gb SSD
4Tb HDD
and a full build would still come out to less than 4 grand.
I think that statement is perfectly applicable to the Panther 5D.
