Cooling the water once the system is off.

[nomad3700]

You guys have any thoughts or suggestions on this. I am gonna relay my pump to run with my case power switch. Is there any issue with letting the water cool on its own, or should I leave the pump on and just cool the water that way. I do turn of my PC at night, but may start hibernating instead of turn off.

What do you guys suggest?

Turning the whole system off incuding cooling at once is no problem. Cooling will stop but so will the heatsurce, so it will just slowly drop to ambient temp andthere will be no issue.

I do not recommend shutting down the cooling and keeping the system in hibernate though, allthough it probably would work as the heat would dissipate a bit though the water system. it would all boil down to how much heat is generated while in hibernate modus, which I don't really know...

well, hibernation and shut down are basically the same. but in hibernation, the ram is saved to hdd, and on wake its place there instead of boot process.
so, the heat dissipation in shut down and hib is +/- the same

I meant to say stand by, with HDD's and power source running.

Doesn't Stand by also shutdown the CPU and HDDs? It just keeps power to the RAM, basically the same thing as hibernation but the session is kept in RAM so it wakes up instantly.

thats another story. but could you enable the S3 standby? instead of S1?
in S3 everything but RAM goes down. maybe a little chipset logic to keep the ram alive and bios, but thats all. and you get the same no_wait_wake_up response as S1 which is basically a blank screen saver...

as i wrote, there are more types of "standby" depending on bios/acpi capabilities and settings

G1/S3 Suspend to RAM (STR) Standby/Sleep
G1/S4 Suspend to disk (STD) Hibernate
G1/S5 Soft-off (power off) Shut Down
G3 Mechanical (unplugged) off Shut Down
