People who use AS5 with Intel C2D dual cores!!

[Duvie]

If you are using AS5 and have a dual core processor dont expect the old instructions of a small dab in the middle to work...

Take the time to read the instructions at Artic Silvers website...Dual core now take a line of AS5 in the direction of the cores under the heat spreader...My reapplication of one of my cpus after follow the new instructions resulted in 6-8c better temps under load...

thanks for the tip... me, i just use the spread a super thin layer over the whole chip method.

my temps have been good...

but if this new way is better, i might have to check it out. thanks duvie!

I used to do the EXACT same thing; in fact, I've not tried this new method on my C2D chip yet and that may be why my temps are higher than normal.

My rationale is: The heat spreader is just that. If the entire heat spreader is making contact with the HS, it makes sense to cover the entire heat spreader with TIM in order that it may most effectively mate w/the HSF.

Apparently, the AS folks know something I don't. Duvie's had good luck with this method; I'm going to try it this weekend.

i used the old method for my FX-60 and it doesn't seem to affect my temps, check them out -

I tell you...the fins on the AC Freezer are so close together that even 1500rpm on the fan produces a very audible low-pitched hum.

In contrast (to the semi old days) 1500rpm on a 92mm Panny mounted to a SLK900 was almost silent.

Admittledly; I've been spoiled over the past few weeks by my new P180; I moved from an Antec 1040 case (not a missprint...it was OLD ) with 4x80mm fans to the P180. Like night and day. Quiet is GOOD.

 

[Duvie]

Spreading over the entire IHS may not show an advantage of using this new method...however if you put a dab roughly the size most did with the single core A64's days and apply the heatsink then remove it and look at the spread out...it will not necessary cover both cores effectively....

In the event the IHS on the cpu is concaved one dab in the middle may not get compressed enough to expand very far from the center...Hence I think AS realized this, and why now they show doing it in a line that can be compressed each direction for a better chance at spreading over the outline of the cores underneath...

 

[TheRyuu]

Not if you took off the IHS

 

[cmdrdredd]

*shrug* tried it...no difference at all.

I use to do that but AS5 has the continuity of peanut butter and I found it hard to spread evenly and thin....So I started to adopt the method of a round drop in the middle....

i can usually get a good even spread except for maybe along the edges at times but it's been good for me...

next time i'll give the other method a try.. assuming i don't run out of as5.

You need to add Intel in front of dual core because the AMD dual core is still a dab in the middle on the AS website. Even then a dab in the middle of an Intel dual core will cover the core just as effectively as a line of grease (if you apply enough) and temps differences should be negligible. IMHO if you're seeing 6C-8C difference between a dab and a line you had other issues.

Here's a picture with both of the application methods

thanks for the headsup!

I didn't have any issues...the dab just did not spread far enough out...I actually think by the marks the IHS is not very flat either...that being said the line is a more effective way to insure a person will have enough in the right areas...

i will place the link you gave at the top and make the change only to Intel...I though AMD's would be the same...i dont know why it is...

 

[Skott]

I used the apply a rice-size amount to the center and it seems to work pretty good. I do like how Zalman has that apllicator (looks like a nail polish brush) with their thermal paste now.

Duvie, I figured that I would toss that pic together real quick so we could compare both methods. Regardless I am pleased to see you experienced a drastic temp change. :thumbsup:

What do you do with all of those rigs in your sig? Impressive to say the least.

One is my CAD rendering box I couple with a 6800GT softmodded to a quadro 4400+ card....I will put the QX6700 in that box...I alswill be adding a Raid setup for video editing etc...

The second box is my DVD shrink box and overall multimedia box....will be hooked to home theater through wall to Tuner to play my vast collection of Xvid movies and mp3s....Will hook to my 55" plasma on the other side of my office wall...


The third box is just a play touy.....Something that may live most of its life on the desk with me tinkering with things....


All of them Fold and with the advent opf my (2) X1900's and the Quad core I should average by my calculations about 2800-2900ppd....

I will have to try that next time I take apart the heatsink. I did it the old way with a small drop in the middle of the heatspreader. Perhaps that is why one of my cores always reports slightly higher temps.

My theory is that one of my cores is always cooler than the other because the heatsink is on it's side.

I should put the case on it's side(thus making the heatsink stand up straight) and see if the cores line up to the same temp. They both run pretty cool though.

Same here. There's a diff of 2-3C at idle b/t the two cores. Stress temps are usually identical though.

I reapplied the AS in a straight line over the cores as depicted on the AS webpage. That was a few days ago. The machine is in it's first power cycle (OFF) now...it's been running 24/7 (some Orthos too) for the past 3 days. I'm looking forward to seeing if the new application method makes any difference in temps.

Admittedly, I had too much on there before...I had it slathered all over the IHS. We'll see.

 

[sbuckler]

AS website says put a grain on, put heatsync on and twist. You can't twist a 975 heatsync when it's pressed down cause the mounting bits get in the way hence the change of instructions I bet. The dual core advice wasn't there when I mounted mine so I put a little bit in the middle, squished it down, took the heatsync off, spread the AS with a razer blade accross the top of the heat spreader to get a really thin layer, cleaned the AS off the top of the heatsync then stuck it down. Worked fine

 

[MichaelD]

Well, I rebooted about 45 mins ago after the PC being OFF for almost 24 hours.

Idle temps seem to have dropped 2C (promising). Been running Orthos, large FFTs for about 15 mins now and the CPU is at 56/55C; about a 2C drop from before as well.

Not bad after just 1 thermal cycle.

But there's always a catch, right? My room temp is 15.3C...in the summer, it's about 25C, which I'm sure will affect the temps.

BUT...here's the best part; my PC is almost dead silent. At 100% CPU usage, the HSF only spins at 1500 (max is 2500). In the Gigabyte EasyTune software, I have the "100% fan speed @" number set to 60C (66C is stock). I could lower it and raise the fan to full tilt but why deal w/the noise? A 4C lower idle temp isn't worth it to me.

What real world apps (even games) are going to peg my CPU at 100% constantly? Very few.

My next mission is to see if I can get this stable OC (@3.2GHz currently) at lower than the 1.320v I'm running now. I just set the vcore to default and ran with it. 1.2-something would be really nice and lower my temps, I'm sure.

I'm happy. I think another few thermal cycles will do me well.

Thanks to Duvie for pointing the new AS application method out to us! :thumbsup:

I think we have to assume the new method yields better results or AS would have never needed to add it to its website....

 

[BadThad]

I don't like either method they suggest. Like it was said before, there's no way to "twist" the cooler with a stock Intel setup. I tried it and took the cooler off a few days later to inspect....hell...it's didn't even cover the whole top of the IHS! Took it all off, cleaned, and did it the old school way by evenly covering the IHS with AS5.

The "dab" method is suck IMO!

Only because you use the garbage HSF from intel.

 

[Thor86]

Using a Thermalright SI-120 hs unit with my C2D chip, and I just only used a small "grain of rice" sized dab of AS5, and no tempurature issues what-so-ever.
