E6600 - cpu air/water cooling compared

**eva2000** · 10-19-2006, 05:13 AM

Swapped out my Pentium D 3.46Ghz 955XE Extreme Edition for my Intel Core 2 Duo E6600 B1 Step 5 cpu to see how well the Scythe Infinity cools compared to other air and water cooling I tried.

Cooling used:

stock Pentium D 2.8Ghz 920D heatsink + Sunon 80x25mm 49cfm fan
Thermaltake Big Typhoon + Thermaltake 120x25mm 81cfm fan
Scythe Infinity + 2x Thermaltake 120x25mm 81cfm push-pull
Corsair Hydrocool 200EX + Thermaltake Big Typhoon LGA775 mounting gear
Swiftech G4 Storm Water + Thermochill 120.3/MCP650 Pump

A few notes:

This is first time i have used my E6600 B1 cpu since i re-lapped the IHS, first lap was half ass job with alot of scratches but this time it's alot smoother and shiny.
Please keep in mind other results were done at different room ambient temps compared to current Scythe Infinity tests.
I'm using a different power supply, before it was either 700W OCZ GameXStream or 1KW PCP&C SLI psu. Now, I am using the new 850W OCZ GameXStream which has 4x +12v rails rated at 20 amps each - of which 2x +12v rails are for independent PCI-E connector power.
I've figured out how to use Intel D975XBX Bad Axe's Intel Desktop Utilities (IDU) application which reports temps, vcore etc. It seems if at any time within a windows session you load cpuz, clockgen etc, you will cause IDU to freeze or hang. The only way for IDU to work properly is if within the windows session you don't load cpuz or clockgen if you intend to run IDU.
Due to IDU issue and fact D975XBX Bad Axe board from bios only allows max 400fsb, it means for tests at >400fsb that require increasing fsb from clockgen, I will have to only use coretemp app to show temps and not use IDU.

System:

Intel Core 2 Duo E6600 QPGE B1 Step 5 ES
Scythe Infinity + 2x Thermaltake 120x25mm 81cfm push-pull
Intel D975XBX Bad Axe rev304 1334 bios
128MB Gainward FX5200 PCI card
2x1GB Gskill PC6400PHU2 HZ Micron D9GMH 0629 batch
3x 320GB Seagate 7200.10 SATAII hdds
Pioneer DVD-RW Burner
1.44MB FDD
850W OCZ GameXStream

How does Scythe Infinity compare to other cpu cooling solutions I have used on the Intel D975XBX Bad Axe platform ?

Max delta & Min delta compared:

Rise above ambient delta = CPU load temp - Room ambient

Rise above windows idle delta = CPU load temp - Windows CPU idle temp

Let's try my usual 24/7 clocks of 3600Mhz at 1.394v bios that I use on water, but on Scythe Infinity air now

Room temp: ~28-31C

Windows idle: 42C

That's around 6-12C hotter than when on water cooling.

**HamidFULL** · 10-19-2006, 07:58 AM

Tanx very very Nice review but I have questions :
1.your E6600 is lapped?
2.Please compare idle and load temp between best Air cooling (infinity + Dual TT fan) vs water cooling
3.you recommend air or water?

**Larry** · 10-19-2006, 08:06 AM

He says that the processor is lapped in the first few notes

1# This is first time i have used my E6600 B1 cpu since i re-lapped the IHS, first lap was half ass job with alot of scratches but this time it's alot smoother and shiny.

**eva2000** · 10-19-2006, 08:11 AM

Yup relapped.. first time i lapped no diff nor any gain in max oc or lower temps when on water. Second time lapping now, never used on air so can't compare if the 2nd lap improved anything heh.

As to compare idle/load temp vs water it's all above in 1st post

Me i prefer water cooling especially with Aussie summer here, but i'm taking apart my water rigs for a clean and rebuild later so Scythe Infinity is a temp cooler

**HamidFULL** · 10-19-2006, 10:24 AM

Tanx eva2000, I seen your are Memory Addict can you help me @ :
I have 2GB Patriot DDR2-6400 Signature Series @ 1:1 1000MHz 5-5-5-12 2.0v
I want to know which chip used for this modules seller told me its Micron D9 I dont want break blue heatsink it void warranty any way to find which chip is used without break blue heatsink?

**eva2000** · 10-19-2006, 10:31 AM

I believe they might be Micron D9, i know the Patriot PC8000 XBL loose latency 5-5-5-5 are as Arctan at http://i4memory.com/showthread.php?p=50424#post50424 managed to get them to 555mhz 4-4-4-9 at 2.4v vdimm

easy way to test is if they do 500mhz 4-4-4-12 at 2.2-2.4v vdimm

**eva2000** · 10-20-2006, 05:39 AM

Update: 24hr dual stressprime orthos completed @3600Mhz at 1.388v vcore with Scythe Infinity air cooling. Here's post load idle temps

**camouflage** · 10-20-2006, 06:03 AM

Wow - nice compario !!! Are You unemployed or what........???

Must have taken a lot of time to do this...........

**HamidFULL** · 10-20-2006, 07:27 AM

First Great Update!

I test it again it can do 940MHz 4-4-4-10 2.0v and 1000MHz 5-5-5-15 2.0v then its Micron D9??

**eva2000** · 10-20-2006, 07:31 AM

hehe thanks camouflage, i work and well i have several pcs connected via kvm switch so can leave one rig priming while i work using other pc which is a flick of kvm switch away

sounds like 99.9999999999% it's Micron D9

Tanx a lot eva2000, where you are active? (which website) I dont want lose you

**kiwi** · 10-20-2006, 08:49 AM

I don't understand why Infinity temps are so bad. I tested mine and it was 5-7C better than TT BT

**eva2000** · 10-20-2006, 09:15 AM

kiwi the temps aren't bad, re-read my room ambient temps for each heatsink test and take them into account you'll see my Scythe Infinity is ~3C better than Big Typhoon

A nice comparison eva!

**eva2000** · 10-20-2006, 06:49 PM

thanks guys... i'm surprised the E6600 clocked to 3600mhz at 1.394v bios on air the same as on water for 24/7 stable especially considering my much hotter room ambients on air now that Aussie summer is here compared with on water a few months back in winter

Seems a good deal hotter than what I have seen on air (with SI-128) at same clock and higher volts on 6600. Probably the ambients...

**eva2000** · 10-21-2006, 07:24 AM

yeah higher ambient temps probably played apart but then again E6600 B1 ES cpus aren't known for their cooler temps, only higher ocs heh

**eva2000** · 10-21-2006, 03:41 PM

How about lower vcore and see how it does ? my E6600 B1 cpu has a default vcore of 1.275v bios (1.25v). I set vcore in bios at 1.3v (1.265-1.277v bios) and clocked E6600 to an easy 3406Mhz (9x378fsb) for dual stressprime 'orthos' testing with Scythe Infinity heatsink and 2x TT 120x25mm 81cfm fans push-pull configured. On water my E6600 did 3550Mhz on around stock vcore 1.25v bios so thought 3406Mhz at 1.265-1.277v would be a nice start for air cooling

Only two changes were made to my system rig:

I swapped from my 850W OCZ GameXStream (quad +12v rail 20amp/rail) psu to my 600W OCZ EvoStream modular (the first EvoStream psu in Australia )
Removed one 320GB 7200.10 SATA hdd as i needed to use it for another purpose. So chanegd from 3x 320GB 7200.10 to 2x 320GB 7200.10 hdds

System:

Intel Core 2 Duo E6600 QPGE B1 Step 5 ES
Scythe Infinity + 2x Thermaltake 120x25mm 81cfm push-pull
Intel D975XBX Bad Axe rev304 1334 bios
128MB Gainward FX5200 PCI card
2x1GB Gskill PC6400PHU2 HZ Micron D9GMH 0629 batch
2x 320GB Seagate 7200.10 SATAII hdds
Pioneer DVD-RW Burner
1.44MB FDD
600W OCZ EvoStream modular power supply

E6600 @3406Mhz at 1.265-1.277v

Room temp: ~25.5-26.5C
Cooling used: Scythe Infinity + 2x Thermaltake 120x25mm 81cfm push-pull
Bios idle: 43-44C
Windows idle: 34C
Windows load: 52-55C
Rise above ambient delta = 28.5C-29.5C
Rise above windows idle delta = 18-21C

All temps still based on coretemp readings.

**Zebo** · 10-21-2006, 04:36 PM

Scythe Infinity is poor mans water cooling. 2-5C difference is nominal and you have a huge radiator and best waterblock made would be lower delta with smaller rad and crappy waterblock... I watercool myself but only because these Scythe Infinity's wernt around when I built my rig, GPU's are in loop, and I go for absolute silence..but really WC is a waste these days from a peformance perspective. Your tests prove it.

**eva2000** · 10-21-2006, 07:49 PM

well at low vcore yeah but water still much better at the max end >1.55-1.65+ vcore

**DarkSephiroth** · 10-21-2006, 09:43 PM

For WC, safe vcore is 1.6?

**eva2000** · 10-21-2006, 09:46 PM

for benching yeah.. i ran this E6600 on water at 3809mhz at 1.5v dual stressprime 24/7 stable
