QX6700ES w/ Coolit Freezone on Asus P5B-deluxe

[Duvie]

Wel I have been playing with this thing for the last few days. I had to get the more expensive freezone becasue the eliminator is actually only rated for 125w which is just a quad core at stock or a dual core with a 10%vcore OC and around 3.5ghz....The freezone gives me 175w of heat dissapation. I am pushing to the edge of that now.

I can tell you high or low seems to make little difference as I cannot detect a measurable increase in noise or fan speed. Overall it is fairly quiet. Still trying to figure ways to mod it for a 100cfm 120mm fan. that will be coming soon.


First things is my Asus P5B-deluxe is a different beast then my DS3 mobo. IN some things it is better like the NB temps, power regulation, stability with fsb and quad cores, etc. hoiwever this board will not give me the full ratio of multipliers like I could get with the DS3 and should get since it is an extreme and ES chip.


Ambient room temp was 22c
All idle temps are taken 10minutes after bootup.
All load temps are taken after 30-60min of 4core loading with F@H (4 instances)
All temps are measured with Asus Probe, coretemp (TAT has confirmed to be identical)

(to be continued)

Going to order an adjustable 120x120x38mm fan with a 120 to 92mm converter and see if more cooling of the coolits HS will help. Coolit does not have a radiator but has something similar to a HS and the tECs are off to one side...They can get very warm.

 

[Roguestar]

Can you post some benchmarks too, please? SuperPi and 3Dmark and such, but just to give us an idea of how it performs when overclocked, clock-for-clock compared to the dual cores. Good results already.

 

[Duvie]

I will, but it wont be superpi 3dmark...

It will be my staple of cinebench, Divx, and TMPGenc....

3dmark is just a waste IMO....I could run pcmark and crystalmark, but other then those synthetics I like to run real world apps that can acually use more then 1 core...

 

[Ronnie]

I would like to see some crystalmark benches.

 

[Duvie]

I will run thiose laters but I still have some playing to do first finding ultimate low vcores at each point that are stable...

I also am going to mod it for a 120mm fan probably tomorrow evening...Reports are 4c drops some where seeing with standard 120mm fan. I am placing a 3 stage Antec tricool on there. At High it is 100cfm. Double what the stock 92mm fan is. This is not a 92x92x38 which I originally thought it would be. It is a standard 25mm thick 92mm fan.

 

[Duvie]

Other mods that can be done are...


1) dremel off some of that large metal shield that block case air coming in from the side. leave enough of it to support the tubing like it is. This may allow air to cool the pump region as well as the inside of the heatsink. It is not a radiator but a finned heatsink


2) you can disconnect the mounting on the pump and move it to the end of the metal cover. This actually will allow you to place a fan on the inside if you wish to push air through faster. May be a balancing act with 2 fans if they differ greatly in speed and cfm...

Seems like your results are pretty close to the results you'd get from a $300 water kit..

I think the only drawback could be power consumption and the potential of burning out those TECs.

Obviously much more easy to set up than a nicely configured water kit. Something to consider for sure. Looks like some quality cooling in a nice package.

Got you 300mhz over your $50 (generous air budget) solution. That is why I still haven't taken the leap to water!!

Great information. Thanks for the post.

Except I paid less then 300...I paid 286.00 and from reports I see I outperform that exact same kit...less noise and easy to setup...It took 5 minutes to set up...Lets see you do that with any water setup.

Kyle at HardOCP in his review said it was better then any currnet H2O setup...

u need a vdroop mod!

Not really...

I mean it loads in windows at a lower then set vcore but uner load it consistently only drops .02v. I call that reasonable.

If I went into windows higher vcore then it would only mean more heat...It is pretty much just semantics....I just have to deal with a correction factor what is set to what I will have entering windows. It pretty much means had I set it to 1.35v (stock for the QX6700) I would have enetered probably no better then 1.33v and loaded to 1.31v...i still would have only been able to do the same speed as I get now. I dont think it is much to be worried about.

to me it is the large drop under load that is to be concerned with.

 

[Shimmishim]

i guess... i just prefer that if i set 1.475 bios, that i get 1.475 or close in windows...

it also helps for high voltage... if you set 1.65 bios, you get 1.56 under load...

anyway... keep pushin... i'd like to see 3.5 to 3.6 on that quadcore of yours

 

[Old Hippie]

Duvie, that's just plain impressive. :thumbsup:

 

[Verse914]

I just got the Freezone a week ago and it dropped my E6600 10 degrees from my already low temp with the TT Big Typhoon. The max Ive gotten it so far is 420x9 (3.78GHz) @ 40 degrees idle. Its definitely worth the $250-$300...

I look forward to seeing what you can do with the quad.

[The-Noid]

I think you are having some good results, keep it up!

 

[Duvie]

Coolit's support rocks!!! Got off the phone with a very knowledgeable person who gave me the run down on some possible product announcements in the next 6-8 months....

There will possibly be a new unit coming soon that will be able to dissipate 300watts of heat versus 175watts of the freezone....

They also make some custom stuff for Velocity micro and have one of their EX6800's running at 3.7ghz with an idle of 14c

PLus they talked about some kits possible with ability to cool video cards as well as the cpu...




I was asking about the fan speed not regulating down (seems at same speed no matter the setting)....The are sending me a fedex package with a NEW TCM controller to try....


Very nice. nice to actually talk to someone who wasn't an arse and act like you are a complainer. We bullshited about product and how well it is doing on my system and C2D's in general. They seem to be happy at how well this thing is still selling and dominating in the market when it is actually a 2 year old product...

here is to hoping a 300watter comes very soon...

I am telling you a closed loop liquid system like this that takes minutes to install and start running is very very nice!!!

 

[Markfw]

Cool ! (pun intended)

 

[n7]

Very nice to see your results Duvie, thanx.

I am a bit concerned about noise still, as i have deliberately gotten a very quiet PSU & case fans, CPU fan, & GPU cooler.

Price also is rather highish IMO, but i guess it's pretty good considering the results.
