Cutting power to discrete GC

nikhilmitta · Apr 9, 2013

Hello,

I would like to turn off my 5770 as I am currently not playing any games. I have switched to the IGP but the discrete GC is still being powered. Being summer, the temperatures are up and I keep hearing a beep from my chassis every few minutes due to heat issues. How do I cut power to the card?

CPU : 3570K
Mobo : Z77X-UD3H

Thanks.

Unplug it if you want no power going to it. As in take it right out of the system. The pci-e lane is still providing power.

Why not just fix the heat issue? The 5770 doesn't emit that much heat so if it running makes things to hot you have bigger issues then that.

remove the card, summer is not 1 day, so the effort of removing the card is worth it, just put it back in when you want to. problem solved. no power consumption from the card

I don't want to invest in a new case. I have a basic one with two fans that just blow in air. Tried to reverse the flow but couldn't succeed (the forum couldn't help me).
I was hoping there was an easy solution to this. I thought disabling the card in Task Manager would do the trick, but didn't. If removing the card is the only option then I will do that. I wonder if there are any good games coming out soon.

You couldn't succeed in turning a fan around?

You usually want the low/front fans to blow in, and the back/high fans to blow out. I would think even with a basic case you shouldn't have heat issues so bad it needs to beep/shut down.

What part of your tower is complaining? If the CPU is running hot then maybe you need to reseat the heatsink. You seem to have recent parts so dust shouldn't be a part of the problem. I've ran a CPU and GPU just fine in the summer. You shouldn't need to remove the GPU in the summer. That's not part of computing.

My case has only two fans to the side, both blow in. I don't see any way of reversing the flow. Tried to change the polarity but the connectors won't mate then.

The display on the case shows the temperature inside the case, not of a single component like the CPU etc.
I have configured it to beep when the temperature in the case reaches 40C. Is that too low? Just to make it clear, there is beeping but the system has never shut down.

You can reverse a fan's airflow by physically unscrewing it, flipping it around, and then mounting it to the case again.

You can use various temp software to monitor the temps of the CPU and GPU. PC probe, speedfan maybe. I'm not sure what's good these days. 40C is fine for a CPU. High for a system temp. If you set your CPU temp alarm for 40c it's a bit to low. My CPU with a coolermaster hyper 212+ can hit 42c.

I cannot screw it back after flipping the fans. The fan casing in such a way that it is not possible.

The 40C that I am referring to is the temperature inside the chassis, not the CPU temperature. Is that setting too low?

40c for a system temp is ok, maybe even a little high. Side fans blowing in is fine.

What case do you have? 40c system temps even in summer seem high.

It is some generic case from Zebronics. Should I set it to beep at a higher temp if 40 is ok?

4745454b · Apr 9, 2013

If it's CPU/GPU temp then yes. Not sure a system temp should be more then 40C. Try setting it for 45 or 50C and see what happens.

Zebronics, India region? How hot are the summers? I get the feeling my summers in North America are a bit cooler...

nikhilmitta · Apr 9, 2013

The temperatures where I live can go upto 45C. I believe the temps seldom cross 40C there.

4745454b · Apr 9, 2013

I'd set it for 50C then. Try to keep the CPU below 60/65C if you can. I'm not sure what the 5770 is rated for. 75/85C?

Thanks, I will set it to 50C.
