However, I'm not celebrating just yet. Booted up speedfan, it says Temp1 is at 50C. Should I be worried?

That's a bit warm but not necessarily catastrophic, what's it like under load?

What's the processor, and what load are you under? Open up that resource monitor.

70C under heavy load is considered a safe maximum for most laptops.

Intel Core i7-4710 (2.50GHz / 1600MHz 6MB) I don't have anything opened up apart from Winamp and Chrome.

With programs opened up or not, check your resource monitor. I would bet it's a problem with the dynamic overclocking or some background processes (It's a new laptop, there are going to be background processes you need to get rid of) that keep it from idling.

You can set a minimum load either through the BIOS or the power settings if you're using windows 7/8, and with Intel's dynamic overclocking, sometimes it just won't drop down to idle and stays around 50C all the time.

I would be much more concerned if it was peaking over 70C under load.

That processor is rated for 100C, 50C is fairly normal, you can help keep it on the cooler side by having all the vents exposed and keeping the laptop on solid surfaces like wooden tables and off couches, carpets or beds. If anything it will be another component that will fail before the processor likely the GPU if you have one and are not running off the on board one in the processor. The computer will shut itself down though when things start to get to hot for it to handle.

My macbook pro goes up to 80°C under load and it's said to be normal. It's been this way for years.

70C seems a fairly low temp under load. I've read reports of mac users with laptops going in the very high 90's under very heavy load, now that was a problem.

Intel lists their Haswell CPUs having a safe peak of 72 degrees. For consumer laptops, that's what you should stick to and what it is programmed to do safely.

Now, the i7-47xx series is the world's greatest overclocking processor that can still be used in a conventional computer. Intel's official "This is where it starts throttling" is 105C . This is where the processor is designed to stop increasing its temperature. But if you want long-term reliability, maintaining 72C seems to be their safe limit. Basically, they built an engine that would go to 12000 RPM but limited to 6000RPM so it can go 400,000 miles.

Since most computers are now using aluminum casing, there's basically no difference between Macbook Pro Temperatures and the temperatures of other (arguably cheaper) processors. The heat sink and fan design affect how quickly it reaches those temperatures and how much performance it can get.

Macbook Pros currently use the previous generation I-series (Ivy Bridge) which aren't as power efficient as the Haswell architecture, but are basically the same. They just released the Macbook Pro with a 4-gen Haswell processor a few days ago, interestingly enough, about a year behind everyone else. It ultiamtely comes down to the fact that Intel is so good at building processors, that it isn't performance or cost effective for Mac to design their own.

Also, I looked it up, Intel's standard safe temp is 72C, but it doesn't start throttling until 105C.
