You can underclock all Nvidia cards since 2012 with Nvidia Inspector. Halved memory clock and core clock for a 1070 lets it be cooled passively without a heatsink (not recommended).
270X is a 2GB GPU. That is useless for Crossfire. Disable one of them and use MSI Afterburner to underclock and undervolt.
That TV is 1080p60hz, which means a 1060 and above is overkill.
Edit: turn off turbo boost for the i5 2500k in windows power settings.
For recent Nvidia cards, just use MSI Afterburner and set the power limit to -50%.
Any reason he doesn't just deal with the real issue and buy a window AC or something?
A small 5.5K btu window A/C unit for a ~300sf room costs about $50 a year to run, according to the energy efficiency stickers of a few selected models.Pumping less heat into the room is dealing with the issue, just in a different way than you propose, and arguably better.
It seems to me that pumping less heat into the room while consuming less power and getting better overall performance is a far better plan then keeping your heat, power consumption and performance the same while incurring the added cost of an AC unit and the 5x additional power it's going to end up consuming.

Perhaps it's not even possible to install one, though?

Maybe even see if he can get somebody to trade his 2500k for a 3770 non-K?Edit: turn off turbo boost for the i5 2500k in windows power settings.
I would leave the computer off for a day, and see if it changes the room temp.The costs can be debated depending on the unit purchased, size of room, average run time and cost of electricity in the area. What cannot be debated is that you are increasing your costs and maintaining the same level of gaming performance vs lowering your costs and getting better performance. The only question is, will the reduction in heat be enough to allow the end user to be comfortable in his own room? If it is, then it's a no brainer.
Sure, but the amount of waste heat you're talking about is tiny compared to what a modest AC will remove. Plus you don't have to compromise on gaming performance and get to be more comfortable all around. Win-win. If you're worried about it from a cost perspective people are taking about crippling a 1080 for gods sake. I mean I hope the dude is running all LED bulbs in his room, has thermal film on windows, etc. There are a lot of physical heat management methods we could talk about before getting into trying to reduce your gpu power consumption.
