Isn't 52C a bit too hot??

Yeah those temps are a little high!
It was hot in my office yesterday and the miner still only got to 45.
HIGHLY recommend adding fans to the other side of the radiator to help cool it. I did that to mine and temps stay around 40 when room temps are normal.

Ecnad is definitely right that is high temps to run. Not horrible, but high. If you add decent fan's on other side you will get a significant improvement on temp. You also could replace stock fans as they are nothing special, just cheap fans with that kit. So if you could get a deal on 6 with high RPM's you chances are would be set.

It was above 94° in my backyard shade yesterday so I dialed up the C1s' pump/fans power supply to 12.45vdc, perhaps higher. Some time in the middle of the night the supply failed. This morning one C1 was running one not, the one running had a highest temp of 80°C. The two C1's are in series cooling. Shut them down, swapped out the supply, and they are both up and running normal speed and temps. They've only been up 9 minutes so it might be too early to tell if they're both okay but looking good.
My mistake, both were down according to the pool. Perhaps a board hit 80°, hashing stopped but the recorded temp remained?

That's what happens when they hit 80C, they'll freeze and the status page will usually remain as it was when it froze. 80C still isn't that hot for these chips and the rest of the board components had the fan going so shouldn't be a problem. 80C is just an arbitrary "well if you've got this hot, you need to come check something so I'll stop here" point rather than "damn, we melting".

Most likely you would know in around 30 minutes or so if they go to lower hash when running. I am not sure series is the way I would go. I still like mine separated. But hitting 80 C is horrible for a miner, we are talking very very bad. If you have this happening you should watch closely, and possibly add some kind of cooling or fans.

Do you have only one radiator for two miners? I don't understand how you can hit 80C. How do you change the voltage? (12.45v)

I didn't use anything special I threw some 2000 RPM fans I had laying in my parts. I did use this adapter to got from molex straight to 3 pin adapters - http://www.amazon.com/Phobya-4-Pin-3-Pin-Splitter-Connection/dp/B007S3T4O0/ref=sr_1_4?ie=UTF8&qid=1431486775&sr=8-4&keywords=3+pin+fan+splitterWorks great for me.

Most of the ones I used were very cheap or free after rebate fans. They worked fine as long as noise is not a issue.

I also used cheap and cheap fans on the back side and it really reduced temperatures. That unit was being fed very warm air in though so those with normal ambient might not see any drop.

I feel good that I'm not alone then on having good luck with just regular fan's. Tiger direct use to do free fans after rebate all the time. I did that and risked some cash, but eventually got rebates. It's a YMMV thing, but it's paid off having just some cheap fans when I need it.

It hit 90 here today... I was fine alllll night
then this morning at 6am I boiled over, my pressure in the blocks was SO HIGH the plugs on the end of the taps were leaking.... WHOOPS.....
Make sure you're adjusting the water level/pressure in that bad boy with summer coming... Boyles law and so on...

Do you have only one radiator for two miners? I don't understand how you can hit 80C. How do you change the voltage? (12.45v) Two C1's, cooling in series like this: C1#1 -> radiator -> pump -> C1#2 -> radiator -> pump -> C1#1. Pumps and radiator fans on a single separate adjustable power supply which failed. I realize an improvement would be two supplies, each with half the fan/pump load with the C1's still in series. That would provide a failsafe on either pump, or either fan/pump supply. It would mean some fans from each radiator. As it is I have a car AC condenser after C1#1 before the pump to C1#2 and had a single 3 fan radiator after C1#2 and before the pump to C1#1. I got in a second 3 fan radiator and since the car condenser was cooling more effectively than the single 3 fan radiator, I put the two 3 fan radiators back to back in series before the pump to C1#1. I'm thinking of adding fans from my shut down Saturn to the condenser. So if I go to two supplies driving my C1s' cooling this summer, I could have one of the two 3 fan radiators and the additional fans going on the condenser and one pump to one supply and the rest to the other. Point being if the fan load on each weren't split and one supply dies then one C1 would be getting hot distilled water from the other albeit after passing thru a radiator or condenser.

Okay...even worse now. The fan on my miner never turns off and there is a red light near the ethernet connector. Can anyway give me a stock C1.img or a network.conf with DHCP? ASAP

It seems deliberate as if to dissuade.
And no, simply flashing the card wouldn't give me the fix I need. It would be in the .1.0 network after flashing the card unless you have an idea how to reset the 192.168.1.99 to another subnet on the card before it goes in the machine.
So, no. Holding the reset for 90 seconds brings it to that, 192.168.1.99, state.
The S5's wake up to DHCP so subnets are not a problem. But water cooled has lower temps than hard fan like the S5.
My C1 image with DHCP setting www.perearstike.ee/C1/C1first.zipYou can use it.
