Unusually low GPU temperature.

I have a GeForce GT 740. Recently, for some reason, my GPU decided to fail on me while watching a twitch stream and it forced me to turn off my computer. After this, I opened up my computer, took out the GPU and did a little dust cleaning. When I put the GPU back in and rebooted my computer, I noticed my GPU temperature was much lower than usual, like 40C. Typically it's around 60C when I'm not gaming. Even while gaming, it barely gets past 50C when it's usually between 70 and 80C while gaming. Did something happen to my GPU after it crashed? I'm using Open Hardware Monitor to read my GPU temperatures.

You kind of answered your own question there. The more dust is in your PC(especially on heat sinks), the less effective cooling becomes, so it's important to clean the dust out of your PC every once and a while(I'd say twice per year at least).

What Air just said, the dust on your GPU made it harder for your cooler to cool the GPU, meaning the dust would stick to it and would cause the heat to settle. Make sure to remove the dust regulary to avoid this issues.

It's not really advised to rely on Adware anyways, their values aren't always true.

I've cleaned out my computer before and my GPU was almost never below 50C afterwards.

There is no problem with your GPU having a temperature below 50°C. It's better to have a low temperature than a high temperature. The high temperature will just cause more friction inside of the GPU, causing failures and/or possible frying of your GPU.

There is nothing to worry about if your GPU has a temperature of 40°C, it's a good thing! :)

EDIT: Here are my values:
GPU: 33°C
CPU: 25°C
Mainboard: 33°C
Fan Speed: 1500rpm
Note that I have watercooling & fan cooling.

I just kinda doubt that it's actually 40C, considering how hot it is in my apartment. Also the temp rarely changes, always between 40C and 45C

This literally made my day. 😂😂😂

Why's that?

Well the max temp under load will vary on the game; it's not always going to be really high.

But it should be below 40*C around idle or lite loads in OS Desktop, that is normal.

Overall comes down to the load being put on the GPU and such; some games you might see 80*C and some you might only see 60*C

It doesn't mean that because your appartment is quite hot, that your GPU will also be hot. The fan is there to provide the cooling to it, thus lowering its temperature.

That depends; if it's say 90*F outside, the room is hot, no AC...
Even with just a room fan and windows open, it wouldn't be enough; cause all you'd be doing is pushing around hot & humid air, not actually cooling down anything. So yes the CPU/GPU (and other parts) would be hotter, cause you can't go below ambient.

So at an ambient room temp of approx 28-32*C (right around 85-90*F) which can be typical if it is Summer for you, and no AC. So most of the hardware is going to run (at idle) right around 32-38*C for the most part; again that's everything running on air cooling, and with good airflow.
