Lets see what Australian summer does to servers

I thought about commissioning my servers, but I was afraid of the summer we are now in. But now I really don't care. So now lets see what this season does to this server.
Specs:
HP Proliant DL360 G5
Intel Xeon E5345 x2 @ 2.33Ghz
24GB DDR3 RAM
2x 146GB 15k 2.5" hdd's
Wish me luck it doesn't turn the house into a sauna
 
Well its not as hot as the other one, but still hot. Maybe crunching some Asteroids
The Sauna creator
Under Asteroids load: 60C CPU and 70-80C RAM 😱
Idle: 30C CPU and 60-80C RAM 🙁
 
Well I hope everything is working out for you down there during your summer months and trying to keep your machines cool. It's been totally opposite here in the great state of 10,000 lakes where its been cold and having to open my windows helps out a bunch. Today has been an event where the snow has been falling like crazy! So, with the wind and my windows open = cool(er) vid cards and higher clocks and that equates to much better PPD. Not trying to rub it in and all as I Hate to see anyone loose anything due to heat. Try to keep em cool Kiska! 🙂
 
I think I found the best mix for keeping this behemoth running ok. Run 30 minutes, then hibernate for 5 minutes, then startup and repeat. In effect keeping the system within the 70C range. The method using HP's iLO interface! I knew it would come in handy

You do know that BOINC has a CPU percentage-usage option, that you can turn down from 100% to keep the temps down.

It literally doesn't keep it down enough, if you get my meaning. Because with the method I am doing it with, when the system shuts down(hibernates) the fans on this server go full blast until the temp reduces down to 30C which is about 5 minutes. Then it starts up and resuming. Also the server already has the software to do so, in the form of iLO and I did pay the licence for it, might as well use it.
If I had it on without the hibernate, then temp reaches about 90C, but for some reason the server refuses to set the fan to full, it hovers at 45%, even though I have defined the rule set in iLO.
 
I suggest the same thing I use on my laptop to keep it from overheating: ThrottleStop. Turning down the clock speed on Intel CPUs also turns down the voltage if voltage is automatic. I turn down my clock speed, and thus voltage, until I'm in the 70-75C range with a normal fan. But it can go much lower - I once turned it down enough that it could stay in that range at full load with the fan off!
 
Its working after I got in touch with HP support. Apparently for the fans to go full whilst its on, the power settings have to be set to HP Static High Performance Mode. Now temps read 53C under load 🙂 whilst fan speed readings give 100% 🙁. But it validates with CPUZ database 🙂 http://valid.x86.fr/w0k6ym
 
I can understand the CPU getting so hot (before fixing the fan speed issue), but why was the RAM getting so hot?? And how did you get that temp reading?

I hope you're not melting! 😱
What are your outside temps atm?

I am not melting....... yet :hmm:
I am not so sure on why the RAM is getting so hot but it is, I am using HWmonitor to obviously monitor the temp on those modules as well as HP's iLO2 interface.
Outside temp is about 30C on thermometer. Inside however is about 32C.
 
Toasty! 😛

Unusual to have RAM temp monitoring, cool! 🙂, don't think I've come across that before, is that typical for servers?

Quite normal with HP and dell servers that use FB-DIMMs.

Edit: I've just found out that fbdimms frequently run really really hot like 90C

Urgh, 41C temps in Sydney just killed my server. Not that it was processing anything, besides being a proxy for the house.
