Idle: w/ 68F room temp:

32c

50% Load, 42c

100%Load, 53c

???

Just installed it... was hoping for more like 45c full load, 38c 50%

It's at 2.75ghz, 1.53v, 4400+, with a Panaflo 120mmx38mm 86cfm fan, P-180 case w/ 4 120mm fans

These temps are definately high considering the low room temp... wayy high actually.

yeah you need to lap the base and redo the mount

I'd also bet the IHS isn't on very well if the difference between 1 core and 2 core load is 11C :eek:

Take the IHS off and then Lap BT base and you will see a HUGE differnce

crank it down some more, tighten it up.
Put the screws up through the botton of the board and use some wingnuts....

Those little nuts took some time to tighten down.. now that you mentioned it I wish I went and got some... :slap:

I'm in a basement so my ambient is fairly cold.

With my x2 at 2.7 with 1.50vcore I idle at 20 and full load at 38, so I think your temps could be a bit better.

Well there is no way I'm chancing the IHS right now. Maybe in 6 months when the value is down.

Also, lapping (polishing?) the base? WTF, no one's fault here but I don't have that kind of equipment.

Nice 4400 man, 2.75 on air is rather impressive.

Lapping the base isn't that hard to do. go to this thread on a great explanation of lapping (http://www.xtremesystems.org/forums/showthread.php?t=69121&page=1&pp=25&highlight=lapping+heatsink)

Ahhh I see, I thought you'd need a machine sander

So it should make a difference with the typhoon then? I'll have to do it I guess, thanks for the tip

Thanks. I know it was prime stable with my XP90 at 2.64, I dont know about now lol, but its BF2 stable and such as long as the room temp doesnt get out of control, sometimes its 80F+ ambient in here. As long as room temps are at 70 or below though I can play 3D, bench etc fine. I'm not super concerned with Prime 95 but still might try to get it Prime stable sometime in the future

O :) i thought you were prime stable @ 2.75 1.53v, still a nice cpu.

actually the best thing to do to avoid speculation is to calculate the exact thermal resistance........here is a post by eva2000 talking about it....it's fairly straight forward....the red figure is what you're after :)

i'm not sure what TT Big Typhoon's thermal resistance is so you'll have to dig that out..........might as well let us all know too

You are putting 174W through.......so this is probably the limit for that air cooler

:lol: ArcTan and dinos :)

Looks like there's a 0.08 to 0.10v vcore difference between memtest and windows right now for each stage of oc listed above.

At 2808mhz at 1.488v there's 33-34C idle temp and 43-44C load temp from 6+ hr cpuburnin max heat load running. MaxTcase temp this cpu is rated for is 57C. And not sure if it's correct but CBI reports thermal rating is 67W ???

http://www.fileshosts.com/DFI/NF4_SLI_D/results/Opteron144/CABYE_0536_GPMW_1/Gskill/PC4400LE/2x256/758_757/623_2BTA/AUTO/9x/312-312-2.5437-8-22-2223_1.525-1.3-1.6-2.9_3684_9N65_16clk_16x7x/cpuburnin_10hrs_tn.jpg

So with my 28C room ambient temps water cooling C/W

Total watts = (((1.488/1.36)^2 x (2808/1800)) x 67W) = 125.12W

Delta (between cpu load and room ambient) = 44.5C - 28C = 16.5C

Delta (between cpu load and cpu idle) = 44.5C - 33.5C = 11C

C/W = 16.5C / 125.12 = 0.1318 (assuming 67W rating is correct)

Memory wise it's fairly similar on mem controller to my FX-57, as 2x 256MB Gskill PC4400LE max windows superpi is around 322mhz 2.5-4-3-6 at 2.9v.

Dividers do complicate the oc'ing somewhat especially on 623-2BTA bios like 623-3 bios it doesn't like preamble set past 6.5ns as pc won't boot. Same happened when testing 2x1GB Crucial Ballistix PC4000 Tracer and Patriot PC3200LLK with 623-3 bios. 704-2BTA allowed my 2x1GB to use looser than 6.5 preamble though.

Then again with Swiftech G4 Storm waterblock probably need to remount the block a few times to get right clocks as my FX-57 between mounts differed in max oc from 3014-3120mhz!

edit: whoops forgot to plug the FDD power cable back in... probably won't make that much difference i don't think though

Big Typhoon 0.17C/W or something like that?

I just got the Big Typhoon and an X2 3800+ Retail :) Getting 1 hour dual-prime stable so far @ 1.65V. The thing is keeping it @ 50C at 2.7 Ghz! I am very impressed. No lapping or anything special. My XP-90C with quiet fan could do the same temps for a Venice @ 2.8 GHz at a LOWER vcore. Wow, this is more than DOUBLE (higher vcore, 2 cores) the heat dissipation and I am getting the same temperature with the Big Typhoon. If I am running 2.6 GHz and 1.525V, the temps are around 42C. Ambients about 20C give or take a couple.

Crazy! 1.65V on both cores 100% loaded @ 50C is impressive on air, IMO.

Big Typhoon 0.17C/W or something like that?whoa really 0.17 is very good....is that an official spec with stock fan

IvanAndreevich

10-17-2005, 07:02 PM

I think that's the number I saw calculated by somebody somewhere with the stock fan. Take with a grain of salt, it's only an approximation at best.

Agreed, good water is well... very good at removing heat. But for the price? The BT pwns on these x2 procs. They really do shine on the high loads. I still CANNOT believe I am recommending a Thermaltake anything to people

just get a universal block, then you dont have to upgrade anymore...it'll pay for itself in the long run :P

you should go water, big typhoon does not own water ^^

IvanAndreevich

10-18-2005, 10:50 PM

Water is clumsy and expensive and doesn't give you any significant performance over good heatpipe coolers. Maybe 5C lower than the BT? Forget going to lan parties, and changing the mobo will take you a long time. I've had it with water..

Leaks? Recutting the :banana::banana::banana::banana: every time for a new mobo or a new case. Screw it for me. If bother, then why not go phase-change?

Frackal

10-19-2005, 04:42 PM

Well, it looks like the Big T is definitely not making good contact. I opened the case and I can actually shift it back and forth over the IHS lol... so I must not have tightened the backplate enough, and put too much AS-5 on.

Tomorrow I'm going to take it apart again and lap the base.

Next cooling I go to will probably be phase change, I'm sick of AIR, but I dont have 600-900 to drop on it right now.
