Ambient temps - Overclock.net

I've never taken ambient temps in accountability with cooling solutions. Why? Because, I didn't care lol. What do I use to find out my ambient temps in my rig, hardware and software wise?

Some fan controllers have a sensor on them. Motherboard sensors aren't really accurate considering that they're one the motherboard itself and is effected by motherboard temperature.

EDIT: I noticed: When my ambient is around 24C, I idle at 38C. Then I'm at 18C, I idle at 29-30C.

A thermometer in the room the PC is in works good for this. I have a digital one that sits on my desk that has a toggle between ambient and outdoor temp. Got it at Lowes IIRC.

I've never found software, or probes to be accurate.

Why is this mentioned so much when overclocking and stress testing. I always figured any computer in a room @ 75c or under is fine.

75F you mean? 75C would be quite toasty.

I actually have the digital thermometer to see the outside temp, it's just a bonus it reads ambient as well. Knowing the ambient temp is useful because you can see how far above the ambient your load temps are. The temperature delta in other words.

Coolio. Thanks allot bro.

I use a digital thermometer to check my ambient.

Ambient can refer to the temperature of the room, or the inside of the case, or outside temp. You should probably specify; I have even seen idle temps referred to as "ambient", which doesn't fit within the definition at all. Not to mention, idle temps generally occur below 50c; TjMax>50c can only be called "under 50c".

I was referring to inside the case. When I hear allot of people talking about their cpu temps and voltages, mostly one of the first things I see members ask is "what's your ambient temps?" What that has to do with one thing or another I was unaware of, but I don't like to be ignorant to something that's obvious to others. You can never learn too much.

Ambient temps can make a lot of difference depending where you live a PC run in Texas is probably going to be operating in a warmer ambient than mine here in South London. that said the difference might not be as massive hugh as you might as first think because most people use Heating/cooling to get room temps at a pleasant level. But that said even just a few degrees "room ambient" difference can alter the temp in the confines of a working PC case by a larger margin.
I think people really need to considering "case ambient" when comparing temps of heatsinks etc.
