Thought I should update this post. I have switched away from the Enermax Twisterpressure 4 pin fans because I was having a ton of problems with the fans just dropping to their slowest speed even though I had them forced to max speed in the BIOS. This would cause the system to overheat.
And the BMC in this system seems to have died and I can not get IPMI to work anymore, but hey it's an ASRock not a SuperMicro. :-)
I replaced them with Antec Truequiet 120mm fans which are significantly quieter, but it did increase all of the previously listed temperatures by 1C. All the drives are still under 40c, and I have no more overheating issues and haven't seen a single bit ECC error in months now.
Yes, drive temperatures are not good in this case. The drive cage is poorly designed, and the case does not force enough air to flow over the drives.
There are some recommendations to cut a custom piece of cardboard to place near the back of the drive cage in order to force more air through the drive cage. I have not done that but you can read the thread here:
I ended up purchasing 2x Enermax TwisterPressure 120mm fans (UCTP12P) to install on the side and blow against the drive cage. They are 4 pin fans and I intended to do some scripting to vary them based on drive temperature, but end up just letting them run at max. The fans are loud, and it did force me to move the NAS out of my office since I prefer silent PCs.
Here's a dump of my idle temperatures:
bay 7 29 C
bay 6 32 C
bay 5 31 C
bay 4 30 C
bay 3 34 C
bay 2 36 C
bay 1 36 C
bay 0 34 C
Bay 7 is at the top of the case and always seems to be the coolest drive. And bay 2/1 are usually the hottest with bay 3/0 right behind.
I have set up an email alert if any drive gets to 40C, and fortunately for my work loads that has only happened a few times.
Prior to getting more powerful fans, the hottest drive was sitting at around 45c and the system temperature was apparently warm enough that I started getting single bit correctable ECC errors in main memory. After getting all of their temperatures into the 30C range, the case temperatures lowered enough that the memory instability went away.
I've actually not heard of Xpenology before. I didn't look into any pre built NAS solutions, as I really wanted to build my own system for hobbiest reasons. The primary NAS OSes I looked into were FreeNAS, NAS4Free, Amahi, and OpenMediaVault. Of those I decided to start out with FreeNAS as I overall liked the GUI. Since then, I've decided that the NAS4Free community is much more open and welcoming, while I now avoid the FreeNAS forums like the plague. This isn't a slight against FreeNAS, more about the regular posters and moderators on the FreeNAS forums. But the subreddit for FreeNAS is a good place to post and ask questions.
I am definitely no expert on ZFS, but the FreeNAS GUI really made everything fairly painless. During burn-in-testing of the hard-drives, one of the hard-drives in this build actually got some SMART long-test errors. I pulled the drive and RMAed it and the system kept running in degraded mode fine for 2 weeks until I got my replacement. Popped the replacement in, resilvered the ZFS pool and was back up and running with 2-disk redundancy. I admit I giggled like a schoolgirl for a moment.
I'm also in love with ZFS snapshots. I've been experimenting with a lot of services to run on the machine in addition to its primary use as a NAS. So I ask FreeNAS to make a new jail, which gets stored on the ZFS pool. Then once I have my service up and running, I can take a ZFS snapshot. Then, I can start experimenting with settings, etc, and if anything breaks, I can just roll back the ZFS snapshot to a known working state.
One thing I should note: I'm getting about one correctable ECC error every 2 weeks on this machine. I have not yet decided if one of the RAM sticks is bad, or that's just a normal error rate for 32GB of memory. Knowing a little about how ZFS works, I would NOT recommend running ZFS if you can't get a system that supports ECC memory.
Correct, one of the front intakes is an Antec Truequiet 140mm fan. The stock fans that came with the case were more than acceptable in terms of performance and noise, so I didn't replace them. The only additional fans I purchased were the Antec and the 2 fans that came with the Kraken x61.
Plex provides some nice services that not many other systems have yet. I stream TV/music from my plex server to my theater system via a chromecast dongle connected to the TV or a small linux HTPC running XMBC connected to the TV. Plex supports dynamiclly re-encoding audio/video, so I'm able to stream my shows to my mobile phone at a lower quality but within my bandwidth limits. It also provides a web interface and you can remotely stream your own content from anywhere via any web browser. It also has the ability to install channels/addons, like a youtube channel, or a twitch channel. Stuff similar to the kinds of programs SmartTVs have.
I've never used the Z506, so it's hard for me to say. I also haven't used a 2.1 system in a long time.
My prior speaker system was a Klipsch 4.1 system that lasted me about 10 years. I've been very happy with these logitech speakers as a replacement. The addition of a center channel is really nice for both movies and gaming, and its tough to go back to a 2.1 system after having used a 5.1 system.
For normal every day usage, it is totally silent. The fan that turns on periodically in my Yoga laptop is much louder.
The video card fans are perceptible when they kick on but only if the video game I'm playing is relatively quiet. In any kind of action game I usually don't even notice the video card fans. I've never heard the Kraken radiator fans spin up to perceptible levels except for when I was purposfully stressing all 8 cores on the CPU for burn-in testing or one of my cats realized that the top of my PC is warm and was laying on the radiator openings!
I built my last PC back in Christmas of 2009, and this system has replaced it. I try to stay on a 5 year cycle with the desktops I build so this is 5 years of savings into my PC budget.
The speaker system and 24" monitor came over from my prior build, so although they'll show up on the total system cost, they were not a part of my budget. I also got a half-price special deal on the CPU which helped.
Awesome, thanks for sharing!
I'm very curious about what you would do different!
I just uploaded my R5 build here, and there is a photo from the top showing the fans and my 'filler' styrofoam:
The system is so quiet, that the hum from my slightly dimmed halogen can-lights in the ceiling make more noise then this system. The stock case fans are great, and I bought an extra Antec True Quiet 140mm to install in the front (running at 600rpm). The Kraken works amazing in this thing, and when the fans are spinning at their lowest (25%) I really can't hear them. The Kraken fan controls are very good so I was able to create a very nice fan curve where the fans stay 25% most of the time, and only ramp up if I'm doing intensive gaming sessions.
I am using a Kraken x61 installed in the top of a Define R5 and did not have to remove the optical bays to get it in. I did have to temporarily remove the rear the fan in order to get the Kraken fittted and screwed in, but once intsalled I was able to put the rear fan back, and still keep the optical bays with a DVD drive installed.
Edit: The kraken x61 is not wide enough to cover the entire top/open grill of the R5. In order to improve airflow through the case and force all air leaving through the top of the case to pass through the Kraken fans, I pushed the kraken as far to the left of the case as I could, and cut a 2 inch wide strip of black sytrofoam material that came with my PSU to protect the PSU in its box during transport. This fit nicely between the kraken and the top of the case to block off air from coming in/out around the kraken. This helped reduce my system temperatures a few degrees celcius which also helped bring the Kraken to the point where it spins at minimum speed even when playing most games.
