Yes, it's bloody hot. And yes, it's doable. You just need to take it easy. To be fair, it's going to be pretty hot no matter when you go. I've been twice and I don't know that there was much difference in temp between May and Jan!

Don't plan on running around to as many temples as you can in a day. Get up as early and be there when the gates open. Take your time, bring lots of water and plan to have lunch, snooze or whatever during the heat of the day. We actually made our way back to the hotel around 3pm each day and had enough time for a dip in the pool before the afternoon showers struck. That helped to cool things down!

I would also plan on organising a tuktuk to take you around at that time of year rather than anything as strenuous like riding a bicycle.

If you go, also check out the temples further north from the main Angkor area (Kbal Spean and Banteay Srei). Driving along in a tuktuk for an hour or more will also help keep you cool!

I agree with the above advice. It is hot but it sounds as though you're experienced in these parts and know what to expect.
Bear in mind it is also rainy season so make sure to bring an umbrella or buy one of the tiny raincoats that will help a little. And don't wear shoes that you care about.

While you're in Cambodia, you may want to take a detour to Kep on the south coast which is a beautiful, quiet and unspoiled part of the country. There's a 30 minute boat trip to Rabbit Island where you can rent bungalows for around $7/night as well as get massages on the beautiful beach.
