How much difference in changing from my BIX to ???

[wadechan]

Hello All,

My loop consists of:

Apogee GT
CSP MAG pump
BIX 240 w/2 Yate Loons @ 12v 1 in push 1 in pull (due to the single fan Coolshrouds I can't put them both on the same side)
5.25 Acrylic res

Temps are ~34idle and ~45load (Orthos), E6400 @ 3.5 1.45v. As I understand it, the BIX works better with higher CFM fans but I want to keep it quiet. This PC is used for games and I rarely see temps above 41-42 during play according to Coretemp. So my question(s) are, would I see any change in temps if I were to change to a PA or other radiator? And will there be any sound difference with a change?

Thanks!

Yes, but the difference would be too small to warrant the change.
Your temps are very good, you should not worry about that.

To keep it quiet, put 2-2 fans @5V on each side, and check how the temps are.
If they are high for your taste (shouldn't be much higher, though), you can try
the 6V or the 7V trick (6V: 2-2 fans from 12V in series; 7V: using the 12V and
5V of the 4-pin molex)

You must be kidding. Lose the BIP and get the Thermochill for two reasons: 1) drop in temps 2) less noise. Thermochill PA's are optimized for low CFM fans. You won't go bleeding deaf like those who use BIP's and GTS/X's.

It's win/win. You get less noise and better performance. The only upgrade you might need after this for optimal performance would be a DDC-2 w/ modded top pump.

[Frank M]

You must be kidding.

No, I'm not kidding. Spending ~$100 or over for a slight drop in temps and a drop
in noise that could be otherwise obtained with the current rad wouldn't make it
worth for me. You know, think first, buy later... :rolleyes:
I think the Thermochill rads are excellent, but as the rad is already given, there
is an easier and cheaper way to get the temps and noise level near.

[ziddey]

Stick with what you've got :)

[septim]

then get an swiftech mcr rad 2nd choice after thermochills.

fashion your own shroud on the pull side and undervolt fans.

and most likely you'll need to change pumps too.

[wadechan]

12v YLs aren't all that noisy to me, I'm assuming the fin density of a MCR or PA is less so it would be quieter?

What would be your guesses as to the temp change? If I went with a MCR? PA?

This is one of those "I need to fiddle around with my setup just because I can" questions. I'm perfectly happy with it now but will be talking myself into spending some $$$ in the near future.

[ziddey]

why are you telling him to spend any money at all? he can do an upgrade when he truly outgrows the bix

I'm wondering if you're kidding here. BIX GTS's aren't that loud. I have a set of 68cfm AeroCools on mine undervolted to 7v that cool just fine. E6600 @ 1.6V, 3.6gHz is 55C on small FFTs in Orthos. And that was with two 8800GTX's in the loop as well.

But no argument that Thermochills are the best in the biz. Or at least that's what everyone says. Never owned one, myself.

[Bail_w]

your temperature are quite good for 1.45v.

[septim]

wadechan if you don't mind the somewhat loud with BIX rads...
and not to mention the restriction coupled with somewhat weak pump...

maybe you can get better temps with stronger pump and MCR or PA rads...
if you are on the upgrade path and willing to shell out for something better
and quieter to boot...

you have good cool ambient temps there, maybe you can get better than 55c load with new rad and new pump...

it is your choice.

ranker, im sorry pal, i have to agree with frank on this as well.

His temps are pretty good as it is. The radiator is nowhere near stressed, for him to be getting those temps. Adding a thermochill wont help him signficantly to warrent an exchange.

He's better off getting a DDC-2 /w modded top like frank originally suggested.

[ziddey]

The BIX isn't naturally "loud". It's just that you need loud fans to truly make it work the way it should. It won't work nearly as well with slower fans, but if it's working for you now, which it looks like it is, then no reason to change that

On my BIX GT Stealth 360, I have my fans running at 1000RPM compared to 1500RPM stock and get the same temps.

[ziddey]

OP has BIX. You've got a GTS. Fairly big difference there. It'd be a closer comparison if you had GTX possibly, but I'm not entirely sure.

edit: Stealth means it can handle low rpm fans decently

Reading comprehension FTW. I'm the one that suggested the DDC-2. No one else on this thread did.

I answered the OP's question according to his constraints.

As I understand it, the BIX works better with higher CFM fans but I want to keep it quiet. This PC is used for games and I rarely see temps above 41-42 during play according to Coretemp. So my question(s) are, would I see any change in temps if I were to change to a PA or other radiator? And will there be any sound difference with a change?

No where does he mention monetary constraints or how much temp drop he's seeking for his investment. He wants to know if there will be a temp drop with a PA. Yes there will be. Will there be a sound difference? of course, since he can undervolt his yates and achieve optimal performance unlike using a series of rads that are built for much higher CFM rads. There are some of us who will seek that extra 2-3c drop no matter the cost.

If he threw in monetary constraints, then I'd have suggested otherwise. But within his constraints, I offered legitimate advice.

[wadechan]

Thanks to everyone for all the advice. It sounds like I won't gain too much with just a rad change, but will if I change the pump at the same time. Again, it's working great I just wanted to see what the delta would be if I set up a radiator that is designed for low speed fans.

This is what is looks like before I cleaned up the cabling, the radiator sits on top, along the long edge with one fan on each side as I mentioned before.

Reading comprehension FTW.

If you are throwing around phrases like this, look at my first sentence.

" - So my question(s) are, would I see any change in temps if I were to change to a PA or other radiator?"
" - Yes, but the difference would be too small to warrant the change."

Now look at his temps:
"Temps are ~34idle and ~45load (Orthos), E6400 @ 3.5 1.45v [...] I rarely see temps above 41-42 during play"

IMO, his temps are great. The PA could get about 1-2°C better - for ~$100,
and having to rebuild the loop.


Wadechan: I suggest trying the BIX with 2-2 fans on either side running at
5, 6 or 7V. The noise difference will be noticeable.

[Holst]

The only way to make an objective decition on this is to ask the question

WHAT ARE YOUR WATER TEMPS?

Load and idle.

If your water temp isnt much above ambient then there is little to gain by changing rads.
I doubt you will gain very much at all (2-3*c) by changing rads.

You would gain more by adding a second rad into the loop then swapping rads.

[septim]

This is one of those "I need to fiddle around with my setup just because I can" questions. I'm perfectly happy with it now but will be talking myself into spending some $$$ in the near future.

hence the advice for new rad and pumps(and probably a little better temps to go)... because he wants to spend his money...

ergo more quiet setup with better rad and quiet fans, better pump for better flow, etc etc...

That's exactly how I read the OP's post and for a moment there I was wondering what others were reading it as.

There are a bunch of us on these forums that will do whatever it takes for that 1-2C drop (even then I'd imagine it'd be more than 2C). He asked a question without adding any sort of value/performance qualification to it similar to how many others in this forum do like myself, iany, septim, etc.

Most of us here in xtremesystems forums aren't too worried about rebuilding loops either. I'm on my 7th rebuild and I still haven't "finished" to the point of presenting a complete project to the group of guys on this board. It's called xtremesystems for a reason and most of us go to xtremes to achieve the results we desire.

Ok, I've got an idea how to get you up to 20-40°C temp reduction: turn off your
pc and stop posting :p:
As for the other things you said, I won't even contest them as I see you can
only see your points, and not accept others', and this would only go on pointlessly.

and you fail to see that I answered his question tailored exactly to his constraints. We'll agree to disagree and leave it at that.
