overheating

[Luv2Box]

Your car is not running hot, it is running hotter than what most consider normal temp. To say that every Boxster should be running with the needle on 8 or 0 is not accurate. I've owned my '99 for six years and it consistently runs at the right side of the 0 when warmed up. Depending on ambient temp or how hard I'm driving it or a grade it will go to where yours is in the picture and I've had no failures due to temperature.
There is an easier way to test your front fans, let the car warm up and pull it into a dirt field, if you see dust coming up from both front sides they're working and believe me you'll know. Also you should be able to hear your engine fan running when the car warms up and it is located on the passenger side and sounds like a vacuum cleaner when running.
It is a good idea to clean your radiators and condensers as they do accumulate debris and if you do decide to change out the water pump put a new thermostat in as well.
You'll soon find out that the internet is full of owners who recommend to blindly start replacing parts only to find out later that the cause of their problem was something else and they've spent a lot of wasted money.
Find a good independent mechanic that can use Porsche equipment to diagnose problems and see what they have to say. Most will diagnose without charging you then you can decide if you want to tackle repairs and or maintenance yourself or pay them to do it.
