If the board crashed while the hairdryer was aimed at a given chip, they would substitute it. Very high tech solution.
An enhanced approach is supplement the heat gun with use of a freon can operating as freeze spray.
Oh, yes, another slight tech method is to pass your hands close over the components on the board. With experience of a particular board, one which is running much hotter than usual can sometimes be felt without even touching it.
Ah, the good old days. (and, yes, there was both an oscilloscope and a logic analyzer on the bench as well). It pays to use many methods.

Ah but when was the last time you even heard of someone replacing a defective chip on circuit board?

Yes, the skin on the back of the hand - b/w wrist and knuckles - is normally sensitive to within around 0.1 degrees Celsius. That is : one can pass that area over two objects and be able to distinguish which is hotter/cooler to about that tolerance, provided it is not too hot nor cold !! In my youthful days of bush fire fighting we had to 'blackout' or make safe/extinguish the areas near the burnt edge after the fire front had passed. One especial problem was detecting burning roots and the like underground, and yup we used the backs of our hand sweeping over the land like a metal detector ( about a foot above the surface ). A very reliable method .... :-)

Yeah, back in the days I'd surprised my friends being able to detect the color of the chess figure in opponents fist without seeing it, just by sweeping my hand near the fist.
I'm thinking of using something called "Indigo Xtreme". It came out very well in the few reviews I've seen on it.
A problem might be that the procedure to apply the stuff/pad is fairly complicated. And it is not cheap, but I would have to do only one PC.
Skinnee's in the middle of doing a massive test of ~60 different TIMs. I'm linking to the page where he's got his running aggregate of test data. For details of how his tests are done, goto any of the specific test runs linked to in the first page. However the spread between different TIMs (excluding a few really bad ones) is small enough that if you're not going for an extreme OC you'd do better to pick for one that's reasonably priced and easy to install instead of chasing the last half degree of cooling. For that sort of information you'll have to read the individual tim reviews.
What kind of thermal grease is better for CPU/GPU? I'm planning to revise all the coolers in my office, because it's to hot there.
I've been using a TIM called Tuniq TX-2 for years now. It has worked very well. I use this TIM on everything including CPU, GPU, chipset, and mosfets. I've also used Shin Etsu and Arctic Silver in the past but the TX-2 has given me the best results.
For installation, I first clean the heatsink and CPU with ArctiClean and then I put a dot of TIM on the heatsink and rub it in with a coffee filter to help fill in any imperfections. Then I spread a thin layer of TIM using a credit card on the base of the processor before installing the heatsink.

Looks like I am close to being over the hill since I still have mine,but then I must admit it just sits on the work table here just in case
I have made and assembled and burned in many circuit boards in the good old days.
