It's all about the game, and how you play it

The cheaper ones usually have very wide optics, meaning you get the reading from a huge area in front of the gun. Mine has 2 lasers to indicate the exact circle of reading. Just remember the one laser models don't really read from the pinpoint laser dot, but a circle around it with a diameter changing with the distance. You'll get better readings if you know your gun and it's specs.

just to add to his point the one i posted says 8:1 spot size(manual is on it's page along with +/- temp deviation information)

guess i'm late to the party, i was going to reccomend
http://www.harborfreight.com/infrared-thermometer-with-laser-targeting-non-contact-69465.html
as a non contact i've had a good experience with and
http://www.harborfreight.com/5-in-1-digital-multimeter-98674.html
for one with a temperature probe(the decibel measure is also good for finding dying fans before they get too far gone)

philips: No problems, I hope you are happy with what you bought

I'll be listing the same model Bicknellski mentioned (BT-GM700) on Bitmit soon. I think it's very good for the cost. My price will be a little bit lower than from Aliexpress.

Variable emissivity from 0.1 to 1.00 will give accurate readings.

I was very tempted to buy the one from Global BTC (just to use BTC

) but I wanted one with adjustable emissivity.

I'm scouting my suppliers for an adjustable one right now.

Consider painting a small target area flat black. Shoot temps on the same flat black spot every time and you are good to go even on metal. Just a thought.

You will have consistency to see deltaT. Man.

Or maybe a sticker or some McGyver-tape?

Or maybe deep pink......

Anyway, I finally decided on this Fluke 62 MAX+

Info here

I found also some nice Testo guns, but a bit more expensive.

So I am thinking about buying one those thermometer guns with a laser pointer for measuring card temps, and probably annoying my cat.
...
Any advice on what to search for, what to avoid...or a good brand maybe?

To measure exact core temp you need to use hardware thermo-sensor on chip.
All another ways will give you incorrect reading.

But it was a great answer anyway, you should consider a career in teaching

Thanks I suppose, But as ironic as it may seem, I'm in fact nowhere near smart enough to teach.

As a teacher I can tell you... point blank it isn't a measure of intelligence that makes a great teacher. It is having the commitment to find any avenue possible to disseminate information only insofar that the students takes control of the learning and is motivated to move forward. The best teachers know that it is not about their knowledge but how to exemplify, illustrate and allow the student the freedom of choice to learn more.

Oh and this is the one I bought for BKKCoins and the Klondike project. Should be picking it up soon!

This is not good for my Chi... Yifu

I use one all the time on my cards (sapphires) and mobos.
The hottest spots on the cards are 3/4 ways to the back on the lateral centreline. This happens to be on a spot of dense metallic contacts. I dont think the EMR emmitted by my hand at say 37 deg C is gonna interfere with the reading of say 76 deg C from the card, especially at about 3 feet distance.
I have used them extensively in industry to detect hot or cold spots on the innerside of metallic surfaces (pressure vessels, heat exchangers, furnaces, tanks etc) to detect spots of internal errosion or where refractory & insulation linings may have deteriorated.

mine is "UNI-T" and is decent enough for home use, cost about 40 bucks.
No need to go for top brands like "Fluke"

If you do not manage all your rigs from one desktop, these are a very handy tool to have.

cheers,
kev

I was hoping you'd appreciate my long and detailed explanation of why it won't work on metal, a bit more though. XD

I do appreciate the effort, really, no joke about it.

I only asked (why is that?) though because the sentence "don't use it for metallic surfaces" sounded (for me at least) a bit ominous, as in "whatever you do, don't do that", as opposed to something like "it doesn't work on (reflective) metallic surfaces", which is pretty much self explanatory.

Respect.
