Your thing is set to distance to TJ Max. That means you are 77-81 away from TJ Max. You need to change it to a distance of 5 away from TJ Max right?

3ghz??? and a delta of 26C??? hmmm

wut lol? omg man thats stupidily low temps heh. How cold is it in your room? I am also curious because I just got a BIXIII on the way and I would imagine it would be within 2-3C of your GTX

1. Allow your computer to be as silent as possible while maintaining an acceptable level of silence.
2. Achieve as low a delta T (change in temps from idle to load) as possible to maximize overclocking.
3. Achieve a good overclock at as low a system noise as possible.

Basically, my water cooling setup using a Black Ice GTX 360 with 6x Scythe S-Flex E fans runs at a noise level of about 30dBa including the noisy DDC3.2 pump, keeping my Q9450 at 3.2GHz under 52C load per core and HD4870X2 under 47C load with room ambient of 28C. Core idle is actually 39-40C idle and GPU idle is usually 37C. This means that I have a delta T of about 10C for the cores on my Q9450 and 11C for my beastly GPU. This is something that you can only achieve with a TRUE using a 90+ CFM fan and it does not even include the cooling of a GPU. A 90+ CFM fan is usually around 40+ dBa, which is considerably louder than my entire cooing system combined. This is a great example of option 3.

A great example of option 1 would be my HTPC. I have a Back Ice GTX 360 with Scythe S-Flex D fans cooling it and run everything at stock. At a foot away, you cannot hear anything at all.

Option 2 would be best represented by ira-k's old loop before he went over to the TEC dark side. He used a 480GTX with H1A Panaflos and 38mm shrouds if I recall correctly. He achieved an insanely low delta T which will completely annihilate a TRUE regardless of what fan it uses. The downside is that his setup louder than yours, which to me sounds like a jet engine.

I would disagree that water cooling involves a lot of maintenance. After you set it up, you usually do not need to mess with it again save once a year to replace the coolant. This is made super easy with one or two drain ports at choice locations in the loop.

Water cooling is not for everyone and it can definitely get pricey if you buy new parts. However, water cooling components are usually built like tanks and lasts forever, so you can buy used parts on forums and not worry about a thing as long as you leak tested it. The only thing I would buy new would be the pump.

Those are some very excellent points. I've never heard it quite put that way. Rep+!

Also, please don't think I was downing water-cooling in any way. I was just stating why I never traversed that path.

No problems... there are just a lot of misconceptions about water cooling and what it does. Water cooling is only as risky as we allow it to be, basically if we are careful and properly leak test for 24 hours, it is only marginally more risky than air cooling. For some reason, a lot of people either view water cooling as like the end all for water cooling and then are sorely disappointed when their idle temperatures are the same or feel the very existence of water cooling will destroy your computer. It is simply not true.

i'm wondering why his delta is high...26C

look at hardwarecanucks review of the thermalright120

they're delta is 24C from idle to load...

oops i forgot dual fan on the true ...max temp is 49C..lol

It would also depend on what fans he is using if any, how his waterblock is seated, what pump he is using, ect...

xguntherc · 10-26-08

No the Tj MAx is 100c.. so those temps aren't 18,18,14,14 they are 23,23,19,19 and loads are getting near 40c.. but those are still very, very good temps. But I will say that I get close to those on my Q9650 at STOCK speed also. my stock speed at 3.0 Ghz on the Tuniq with it's stock fan I get around 27c idle.

also Oc'n Noob.. I see you said you have the BIX360, and your Q9450 at 3.2 Ghz. and you said that the idle is around 37-40c... personally that would not make me happy. (I'm not trying to bash ur system at all though, so don't take offense. I'm just trying to justify).

I know the idles aren't what matter. and the loads are what matter. but your saying 37-40 idle and 52c load at 3.2 ghz on the Q9450.. I know I have a different chip. but I'm getting that a 4.0 ghz.

With my Tuniq Tower Lapped I have my Q9650 at 4.0 Ghz and idle temps are Currently with FF3 open with 3 tabs, and other screen has the News playin live feed. my sort of idle temps are 37/34/34/34 and thats at 4.0 ghz on AIR. then the blend load temps get to 51c but small FFT's get a lil higher. these results vary with the Room temps also. but currently it's around 75F in my room.

Just saying this for the comparison.. I'm going to try the TRUE and see how it goes.. and not til Monday.. ****!!!!

nafljhy · 10-26-08

even though he says his idle is at like 37-40.. you also need to know that his idle is more likely to be closer to his ambient temperature. so if your rooms is colder, the lower your idles. his room might be quite warm, you just don't know.

also about idles.. the DTS are crap at idle thus totally inaccurate as said by intel themselves. so i pretty much ignore idles now. i look at my loads or the distance to tjmax.

Hondacity · 10-26-08

@xguntherc

good observations, i think the tuniq really performs well..and the true abit better...if you want sub ambient temps...you'll want watercooling as it lets you setup your rads outside for that winter oc...
