Will upgrading a processor reduce the fan RPM?

I have an Intel E5200 Dual Core processor on a Sony all-in-one computer. It is a hybrid notebook/desktop computer.

Whenever I play the Mahjong Titans (the game that comes with Windows 7), the fan runs at a high RPM. When Windows boots, it is at 2150 RPM. After playing Mahjong Titans for about an hour, the RPM goes to about 3,300 and the fan is loud. It always happens.
The temperature of the cores remain at 36 and 38 degrees.

If I upgrade the processor to an E7400 Core 2 Duo, will that processor not heat up as much as the E5200 when playing Mahjong Titans and consequently lower the fan RPM?

The temperature of the cores remain at 36 and 38 degrees.

I am not looking for any other solutions. I have tried everything else imagineable.

Probably Not.

While playing MT, open the task manager and look to see how much of the processor's capacity is being used. I'll bet not much. So a faster processor would not change anything, would it?

It is probably the graphics chip, running a 3D program, that is working hard and creating heat. The "laptop" fan (those hybrid enclosures are just as cramped and therefore will have the same issues with cooling) will run hard if the processor, graphics, or hard drive is creating the heat.

It might not, because if the problem is heat in an overly enclosed space then a more powerful graphics card might make it worse!

I don't know if you can add a "real" graphics card to those systems. I've seen them in stores but have never had the opportunity to open one up and look inside.

Perhaps if you posted the model number of the unit, or better yet, a link to your product's specs page on the Sony website, we could look at what it is and tell you if that is possible.

With no exceptions I can think of, any processor will work with any graphics card. You are more limited by the motherboard, and in your case, the system design.

With those types of Desktops, most of the general rules for laptops also apply. This includes heat. Heat literally destroys electronics. You might be able to turn down the fan speed with software, but I wouldn't recommend it. I'd just be happy the computer is that cool.

They do have systems with the exact same case that come with nVIDIA GeForce 9300M graphics cards.

Yeah, you see, that box has an Intel G45 graphics chip soldered to the motherboard.

And I can't tell from Sony's website whether there is an expansion slot for a video upgrade path (that website is geared for the consumer, not the enthusiast). You could take a look in your manual to see if they say anything about upgrading/installing a video card.

It looks a lot like it is what it is.
