Oh dear... 74C on my Cel. D.

Small problem with that... box runs Linux.

There's probably SOME equivalent, but who knows where...

I'm tempted by thermally-controlled fans, but after the lovely noise DISASTER the stock Intel HSF was for this precise reason, I'm weary...

This Zalman fan, I assume the case has to be opened to adjust the speed?

Okay, found fan controller app for Linux...

How should I remove Zalman's thermal paste?

Can one container of AS5 do multiple installations? I must admit I'm so pleased with the Zalman, noise-wise, that I'm considering getting one for my 1.9 Willamette box too... (though I really should be spending my money on an X2 to replace that with...) so if I could use the AS5 for both, and perhaps the upcoming Athlon, that'd be good...

On 3.5g container is good for about 20 to 25 applications

You can just use 99% isopropyl alcohol (I use 99.5% straight from the lab ) or acetone with coffee filters/cotton swabs if you don't have any AS remover . . . works fine for me . . .

BTW, after 5 hours at full load, the two non-CPU temperatures are still much lower than yesterday...

Somehow the missing 12V and/or some extra cable clutter I cleaned up were making the motherboard run 10-20C warmer.

 

[1Dark1Sharigan1]

That cable clutter was impeding your case airflow . . . cable management can make a BIG difference when it comes to airflow and case temps . . .

Well, here's what I did:
- took the 12V cable that had been stuck between the 5.25" and 3.5" bays and plugged it back in
- removed the cable to/from the Zalman fanmate 2 and hooked up HSF directly to motherboard
- removed a 3 pin to 4 pin adapter and hooked up rear fan directly to mobo (with the 12V out, it was easy to get it in...)

Did those three things really improve case airflow that much? They seem pretty minor to me, but perhaps not...

Easier to tell if you have pics . . .

From the looks of it though it would have helped airflow some but not 10-20C cooler as you mentioned . . .

I actually WAS going to take pics, but then completely forgot...

Besides, do I really need to embarass myself further by posting a somewhat messy picture?

 

[1Dark1Sharigan1]

lol I suppose not . . .

But yeah I say just be glad your system is cooler now . . .

Yup...

I'm almost tempted NOT to do the Arctic Silver thing... current CPU temps are about 58C idle, 72C after sustained 100% load. Motherboard or case or something temps go from 38C idle to 41C under load; some other temp goes from 40.5 idle to 51C under load. Seems perfectly stable. And it's no longer the loudest box in here...

(Random off-topic rant: I should never have built a MythTV box... biggest money pit in the world, that thing... and it's still missing a second TV tuner and a DVD burner... and I need money for an X2...)

Well AS5 should drop those temps by some but not by THAT much . . . you'd need a better HSF to see a significant temp drop . . .

I would say it's worth it though . . . ten minutes well spent IMO . . .

Ten minutes? You must be an expert at this...

I'll probably grab AS5 and the cleaning thing next time I go by the store...

(And what's a "better" HSF compared to what I have? that monster Zalman 9500?)

Expert? Nah . . . I've probably done it maybe twenty or thirty times but I don't think that qualifies as expert . . .

Since you're using the retail HSF, you just need to clean off the old thermal stuff (should take no more than four or five minutes) apply some AS5, then reseat the HSF. 10 minutes sounds about reasonable.

Well the Zalman 9500 would be better lol but probably not what you're looking for. I would say an XP-90 is the best HSF since it's relatively inexpensive (roughly $30 USD + fan), easy to install and light . . .

No, the retail HSF is gone (and sitting on my desk)... replaced with a Zalman 7000AlCu-LED.

Noise way way way way down, temps a bit up...

LOL I suppose I need to read the previous posts. Well even with the Zalman 7000 it shouldn't be all that hard.

XP-90 is still much better than that Zalman though . . .

And XP-90 isn't available at the local store... (or at least, not at the one I check...)

The Zalman is the weirdest thing in terms of installation, simply because it feels like the screws aren't long enough, but they turn out to be...

 

[1Dark1Sharigan1]

Ah yeah, I haven't used the Zalman but can't be more complicated than the Tower112 or Big Typhoon . . .

 

[zagood]

31c is a HUGE difference between case temp and processor temp. I really think cleaning/reseating is going to help you a ton.

Love Zalman, but gotta admit the XP-90 is a great cooler. The main difference though ends up being which fan you put on it...which is the question for your back 92mm fan anyway.

Have fun at the store! Make sure you follow the instructions EXACTLY for cleaning and applying.

Even though those temps are better than you had before, I agree with zagood, I think you could see better temps than what you have now by reseating the HSF. On my computer at work, I had to reseat the HSF twice to get it right. I was having a little trouble getting used to the Intel 775 socket retension clips. But once I got it, the temps where much better.

After cleaning the HSF, place some AS5 in the middle. Then put a plastic bag over your finger and smear the AS5 around the area in which the cpu will make contact. Then take a coffee filter and wipe the excess AS5 off. This will fill in all the micro grooves. After doing that, place a small (2/3 size of uncooked rice) amount of AS5 on the middle of the cpu. Place the HSF on the cpu and mount it. Do not lift the processor off the cpu as they say this can introduce air bubbles between the HSF and CPU. Thats just a little of what I remember reading on the Arctic Silver website, I would suggest going there reading over the instructions for the AS5 for a much more complete write-up with pictures.

 

[Jojo1971]

my advice to you:

install a 120mm (@ 7 volts for silence)side panel fan.. it should drop your cpu and case temp alot...make sure you have a at least one 80mm fan in the front ...you may remove the fan in the back and leave the hole open...
.

keep your zalman-it should be good enough for a celeron D...

if you happen to be thinking of getting an expensive HSF , why dont you just sell that celeron D and use your $$$ to pickup a used P4c "Northwood" from the forums? you can pickup a used 2.4c @ 3.3 for about $90-110 in OC or AT FS/FT forums... just MHO..

At this point, I'm not planning on picking up anything except the Arctic Silver stuff... At some point, I have to stop throwing money into this MythTV experiment, especially when my main box (1.9 Willamette P4) is starting to badly cry out for an upgrade...

Wow, that's very high. My Cel D @ 3.62 with a slight vcore increase loads at 46 C with a Big Typhoon.

That's because it is a Big Typhoon, all copper with heatpipes and 120mm fan. The Zalman the OP was using is mostly aluminum with no heatpipes and 92mm fan.

For the OP...

I used to run a Prescott 2.4A on an Abit IS7 overclocked to around 3GHz with a Zalman 7000AlCu (non LED). Load temps were well into the 80ºs Celcius. A few thoughts for your situation...

1) Cleaning cable clutter always helps.

2) How cool the CPU is depends on how cool the air is inside the case. If the air gets too warm in your case, the best air cooler in the world won't help. I think part of the problem is the Vantec Stealth exhaust fan. My suggestion would be to get a 92mm fan as suggested by someone else and use a fan speed controller on it to get the desired noise/performance balance. You can use the Fan Mate included with your Zalman because...

3) The Fan Mate included with your Zalman reduces the speed of your fan by a bit even if it is turned up all the way. If you plan on using the fan at full speed, don't hook up the Fan Mate.

4) I've found that proper application of heatsink compund to be more important than the actual brand/type of heatsink compund you purchase.

5) I don't think the Celeron D does any throttling. The Pentium 4 Prescotts do that, but only the ones 3GHz and up.

6) Abit motherboards seem to report temperatures higher than other brands.

Okay, so if yours went into the 80C range, and mine (2.66GHz, less cache) is around 72, then does that mean I'm actually not doing too badly?

1) I've tried my best... the thing has rounded cables, too, for HD (yes, I should have gone SATA...), optical drives, etc.

2) So what 92mm fan to get? I haven't found too much available around here that's an improvement over the 27CFM 21dBA fan in there now...

3) That's why I removed it...

4) Based on your experience with the same motherboard and cooler (and similar CPU type), would you conclude that I applied it wrong? or would I be wasting $20, time, and the risk of breaking something by redoing it?

5) So what happens if it gets too hot? Mobo kills the power, end of story?

6) Hmm... wonder if that's what's going on here?

Well, yes, I know. However, I also have it overvolted and overclocked by more than 1 GHz. There shouldn't really be a difference of 28 degrees..

Maybe room temperature has something to do with it?

I stuck a thermometer roughly in front of the case... 26C.
