FYI: your basement might be warmer at night

[marvinmartian]

If your central AC is cooling your house in order to compensate for the sun heating it up (and hence cooling your rig in the basement nicely) remember that it won't feel the need to cool as much at night (since your upstairs is cooler due to lack of sunlight).

EG.,  my basement temps rise about 2-3 degrees overnight.

What is this "basement" you speak of . .  . heh

thats one thing I miss moving from WI to TX

2-3* F or C isnt much of an issue.

i run my system in a non-climate-controlled portion of my house. gets to about 100*F in there. temps for my 4x gpu's are sporadic due to the strange config and my lack of fans having direct contact with the GPUs that are "sandwiched". 64-75-78-78 *C right now with ambient temp of 93*F. run 80% fanspeed.

at 100*F ambient, max card temp is 84*C. should be able to knock that down quite a bit when i toss a couple high CFM 120mm's. lowest is 70*C, its the card on the outside.

I wrote a script to shut off your miners at a given temperature.

I dont know about you but my basement is still a heck of a lot cooler as night than the upstairs.

Disturbing post.

You bathroom too can get warmer at night, especially when you have 5kw of hashing power in there.

In Austin, Texas, many older homes have pier and beam construction which permits the easy access to water pipes in the crawl space under the house.

That's where I put three mining rigs that together draw 860 watts from the socket.  The ambient temperture is a steady 30 C, 86 F, despite recent highs over 100 F.

Here is a recent temperature reading from one of the rigs.  Its 3 hours after sunset.

Code:

user@linuxcoin02:~$ DISPLAY=:0.0 aticonfig --odgt --adapter=all

Adapter 0 - ATI Radeon HD 5700 Series
            Sensor 0: Temperature - 74.00 C

Adapter 1 - ATI Radeon HD 5700 Series
            Sensor 0: Temperature - 65.00 C

You and your fancy "basement" and "air conditioning" and the "upstairs".  I live in a tiny house that cost WAY too much money.  Of course, I am 2 blocks from the beach in San Diego...  

No air, it's only hot enough to need it about 2 weeks a year.  Instead, in the summer we break out the window fans, for daytime.  It always cools down to the mid 60's F at night, even when it's hot that day.  I've been turning my clock speed UP at night.

Since I have no basement, and my house is tiny, I do have to keep a lid on the fan noise.  You are never far from the computer if you are inside.  So 55% speed is about as high as I can go, and down to 40% at night when the window fans are off (they cover the computer fan noise during the day)
