Quick question out of any CPU waterblock (755/1366) which would you say is the best to cool an i7 at 4ghz.
Bloodrage can mount 755 and 1366 cooling hardware.
I was looking at the D-TEK FuZion v2.
I was using the Aqua Di @ 4.4 and it never hit 70C. I cannot wait to see what the HD Di does!
Not sure what is the best, I havent seen a side by side test yet. I assume you want 4ghz with HT. I am running the aqua computer cuplex xt di and at 4ghz with HT 1.35v bios 1.375v windows 1.39v linx load I am 67C max load with an idle of 34C. This is my 24/7. HT adds a bangload of heat into the mix with these things. I see a 5-7C difference with it disabled, you can also run lower voltage.
This is with my PWM and NB on the loop as well. So I would think any of the top blocks dtek/ek etc. would be similar.
Koolance 350 its amazing :D!!
I´m using the Fuzion rev 1, i got 58C with an i7@3,5Ghz 1,29Vcore. I´m currently rebuiling again (drilling some holes in the motherboard tray and remouting vga block) I´ll test 4,0Ghz in the next days. The Fuzion is definatly still very powerfull and fits on the Bloodrage, also it´s the way to go if you have some more blocks/rads in your loop because it´s very less restrictive.
I wonder if anyone has tested an Apogee GT on the i7's.
Any proof on this statement?Quote:

As well as a T line, and Laing D5 pump.
I planned for 7/16 ID with all 1/2 in G15 fittings.
Didnt expect such difference over GTZ/Fuzion. Anyone else has any expirience with K350? Seems to be the best current solution for i7.Quote:

Wow I did not expect that from koolance. What vcore?
Odd, i have had 1.6v through a q6600 and 1.55v through my 920 at 4.5ghz and my GTZ was just fine.
I am pretty sure that is at 1.38vQuote:

Not to put anyone down or anything here, but one glance at that and I already see a problem...Quote:

Sorry, but there's always mount variation and if a test system isn't precise enough to even detect it, then the system is not fit for waterblock performance evaluation. Far too uncontrolled/imprecise to be regarded as anything more than 'anecdotal user data'.
dunno how you mount your blocks..i just tightened them to a point im just hurting my fingers... remounts are easy... i get the same temperatures..over and over...try real temp on the i7.Quote:

easy as 1-2-3...except it takes awhile
My choices would be Swiftech GTZ then the D-TEK FuZion v2.
Danger Den MC-TDX
gtz internal design doesnt cover the entire i7 die though. fuzion, supreme, sapphire, gtx, gt all do. none of them were really designed for i7 though... so in all reality its good that any of them even work.
as for mount testing.... i have gotten temp differences by putting too much or too little TIM. i use the line method but i still get too much sometimes and a remount is necessary.
also... different TIM's do better than others. i personally like OCZ freeze.
The Koolance 350 is VERY restrictive, more than EK supreme.Quote:

If it's true that the 350 is restrictive I'd assume the Supreme would be a better choice? ( I'm going to run a chipset, and latter maybe even a 4870x2 after I get another RAD.)
I don't see the heatkiller on any of the sites I buy from, but what about the Danger Den MC-TDX?
CPU at 4ghz, and x2 at 800/900 almost stock.
Any last minute thoughts? I'm going to order the parts either tomorrow or the next day.
Thank you for all the input.
Look here http://www.xtremesystems.org/forums/...d.php?t=213106
I cannot say anymore about your choice because i doubt myself ^^
But what i m sure, is the K 350 need high pressure pump like DDC 3.2 + Top
[edit] just found this http://www.xtremesystems.org/forums/...d.php?t=217376
The current tests suxxx... :(
but corrected here http://www.xtremesystems.org/forums/...80#post3642480
Let me state this once more: you will always have some mount variation and your statement only implies an even less controlled test environment than I had previously thought. Whether you're properly using the included stock mounting hardware or a custom mounting configuration which applies a known and equal (or, as equal as possible) mounting load to all blocks being tested, you're still going to end up with some variation. You'd get this same information whether you asked me, Scott, Bill Adams, or Lee Garbutt. The best that any tester can do is take the mean of this data, whilst being sure to note the observed data range.Quote:

From a design consideration standpoint, the on-die [point] temperature sensors are little more than an overheat alarm--they just have to be good enough within a certain range so that the CPU doesn't fry. That's it.
same mounting ..same cpu..same temp sensors...same fans speeds..same paste...same pump... oh well...i'm just a noob tester :rolleyes:Quote:
