QX6850 Overclocking
- Thread starter Thorne
- Start date
I was going to get the freezone or the eliminator but heard they were no good for cooling quads ... seems that was a load of old bol*# then.
Interested to see if someone has tried this out on a clocked q6600 if the results are good I might get one of these for the cpu and run everything else through the wc loop.
tried googling it without success anyone else found anything ?!?!

Where did you hear they were no good for quads, I read every review I could find and never saw anything that mentions any issues with quads and I have been running this one now for over a month. I have yet to find any fault apart from the fan is a little noisy.
Its an expensive bit of kit but I think well worth it.

According to the website the Freezone is specially designed to do Quads.

There is a load of links on their website which came up 1st time for me on Google.
The installation video is very professional, although I may be swayed by the blonde who whips the screwdriver from her back pocket with practiced ease. I'd love to think she was a computer/cooling engineer but sadly I reckon she's a professional demonstrator.
And c'mon guys - S478 isn't where your target market is anymore. Your US customers will be complaining they can't screw the CPU retainers into the holes.
It does look good based on Thorne's results, but I would have to think hard about spending £200 on a non-upgradeable CPU cooler. And there is nothing noted at all about condensation, which is usually an issue with anything that cools to below ambient temperature. Look at the outside of a glass of beer that's come out of the fridge at about 4C, it's covered in condensation - how do these guys avoid condensation on the CPU socket when the CPU is idling?
Well worth investigating though.
Have you tried running this chip on air? Maybe this would give you an indication as to whether the temps are indeed correct. The Q6600 G0's are also reading too low (lower than ambient temp @ idle) as are the 6850 dual cores so I don't see why the QX6850 should be any different whether you are using a tec or not. Sure a tec 'should' be cooler but after spending so much on the cooling I would want to ensure my temps were at least comparable and as accurate as can be.

Looked at their website ages ago and there was nothing on it about quads and didnt check in my latest googling run ... everything I read was on duals not quads .... back to google i go then !! for the record it was said that the max thermal blah de blah was fine for duals but not for overclocked quads ... hence my impression.
I just found a really good write up on the freezone, not fully read it all yet but it explains in detail how it works

Thanks for the link - made for a fascinating read. Still not quite sure I can believe it. It seems incredible that 6 7W Tecs can produce the results that we've seen - especailly considering that it's based on an air-cooled TEC system - universally accepted as a bad idea - shows how wrong we can be - it's good that people are willing to challenge preconceptions and try new things!
Keep us updated on your results as you push your chip further - will be interesting to see how it performs as you increase the load - just be a little cautious - if you do overload the TECs the temps can spiral out of control quite quickly and it doesn't explain how the TCM deals with runaway. I'd either leave throttling on or set your mobo to switch off above a certain temp (60C perhaps).
Did you source it in the States or locally and would you mind telling us how much it set you back?

The one bad point I find about the freezone is the lack of temperature monitoring so I am fitting themocouples to keep track of the operating temperature, also since the pump connects to the cpu fan socket its hard to keep monitor the pumps operation since the fan speed gives eractic readings so I am trying to find a better way to monitor in case of pump failure. There is also no way to monitor the fan either , although the noise is one idication I would prefer some way to check it. Its does seem like it has a few negertives point but the cooling I have seen so far makes it more than worth it.
I managed to find it on Ebay , one of the sellers imported a number of them but seems to have had little luck in selling them , I paid £189 for it and am considering getting a second one for another new systems that I am building.
They state 3.6A draw running which would make it about 42W total between the 6 - hence about 7W per TEC - they're probably rated to a Vmax of 15V so it will probably be around 10W max each 
That's the revolutionary bit - by using several smaller ones you get far less waste energy an hence better cooling per Watt - very clever 
Getting me all twitchy again - got several 80W pelts kicking around that I could ghetto rig to a similar system - mmmmmm - ugly-mod - mmmmm

Another good review and explaination of the Freezone

I just bought some 40mm 10.5A 183W Peltier coolers to play with and see what results I can get testing them out

You got the CPU/Gpu blocks and cold plates to go with that (and is it Potted)? What are you planning on using to power it and where you you plan to put it? (GPU?) Have you done any DIY pelting before? Sorry if I'm sounding like a nag, but there are a couple of traps to watch out with using TECs - not to put you off, they are great fun and give good results!

I have used TECs before but its been some time so will read up on the subject again , would be keen to hear any advise you may have. I am planning to test them on various setups and manufacture my own heatsink/fan/water combinations. I have Bench power supplies to use but will also modify some ATX PSU's. Initially I am not going to attach to any CPU or GPU its just to see what the TEC's can do.
Cool - sounds like a fun project - expecting lots of nice pics of frozen tecs/blocks 
The 180W 40x40mm pelts are perfect for GPUs if you want some seriously low temps, especially if you have a bench supply capable of giving you 15v. I'll have a dig about and see if I can find all the old links I used to use - I know the only thing that was a real hastle was setting up the pelt/coldplate/block as it requires a large amount of pressure and it needs to be applied evenly to get the most out of the TEC - luckily the guy I got mine from had already mounted them so I was saved the pain 
What Rad you planning to use to cool that beast?
If you're building it all yourself then you could always try the chiller method your current cooling uses and have The cold sides of the TECs on blocks chilling the loop inside your machine with a Rad cooled loop to cool the Hot side. It'll be big, but might work nicely! The only problem I had with my chiller was the fact that all the pipes had to be lagged, as did the whole of the GPU/CPU block which took a little time, and bending lagged 1/2" tubing is certainly interesting
