SLK800 cooling problems

[SpliT71]

just got my slk800 and cleaned it with 70% achol(all i had) also cleaned cpu, now my temps as reported by MSI pc alert 4 are 45c idle and around 52c load and this is bs...i also have a Tt dragon orb fan(50 CFM), right now i havn't lapped yet because i don't have any sand paper, but do do you think i should be seeing at least the high 30c's low 40c's during idle at least?? any help is appricated

[Jeff7477]

what were your temps before the 800?

[SpliT71]

roughly 49c idle with stock amd hsf load was 55c or so

[SpliT71]

anybody have any expierence with the slk800 they'd like to share? :( i'm at a loss

[ccb056]

what are your case and room temps, also, is the fan on the hs blowing air on or off of it, did u use a heat transfer compound, if so, idid you use too much/too little, is the hs seating on the cpu right, when u run your nail accross the base, does it make a sound??????????????

[james.miller]

SpliT71, checklist:

1) fan blowing on, not sucking off
2) base is smooth and free of debre.
3) H/S is the correct way around
4) you correctly followed the instructions on the artic silver website.
5) those links in your sig arn't allowed

[SpliT71]

1) blowin on
2)yes cleaned right before i put it on with 70% alcohol
3)yes :p
4)yes cleaned with acohol
5) my bad

[SpliT71]

so anybody recommend anything?

[mdcomp]

What is the cfm rating on your fan? I have a 50cfm sunon on my SLK800 and the temps are good.

[SpliT71]

rated CFM is 49...i don't understand :\

[mdcomp]

Did you apply Artic Silver 3? If not, you should.

[SpliT71]

of course, i thought that maybe im doing it wrong, but i put a little bit on and spread it around with my finger inside a plastic bag...is that ok? also should i lap it?

[Wangster]

If your surfaces are extremely flat/smooth, try applying with a razor blade scrapping across the surfaces. They aren't kidding when they mean thin application.

[mdcomp]

Wangster is right a very very thin application is needed. I usually spread it with a corner of paper or cardboard.

Aren't you worried about the possiblity of contaminating the TIM with microscopic paper fibers if you use paper or cardboard?!

[james.miller]

lol. its not an artform. its way over-rated IMO.as long as its fairly even it doesnt matter - as soon as you put the H/S on it compresses the compound and changes shape - so whats the point of trying to get it perfect?

[SpliT71]

lol yea well it does spread so i wanted to make sure i put enough what is IMO??? god it's been bothering me to know :o

[SpliT71]

so anything else i could do?

[Wangster]

Based on the C/W with your CFM from JoeC's review, what temps should you be getting?

[SpliT71]

http://www.coolerexpress.com/therdragorbf.html thats fan i use but not the heatsink...as said in the title i am using the SLK-800a

[attitudx]

just my 2 cents but your process are the L11 bridges crossed or shorted to default at a higher voltage. I was running way high temps and didnt realize it but was pushing 1.8vs, when lowering the voltage of the vcore my temps dropped from high 40s mid 50s, to mid to high 30s at load. Pcalert has the little cooler xp button click that that will lower your temps as well dont know why but it does

[I.M.O.G.]

Do your motherboard sensors report standardly or do they have known issues? Some boards are known to report way differently than everything else.

If there is a problem:

How are you clamping the heatsink onto the chip? With the 4 mounting holes or a clip?

If you are using the bolts with springs you want the springs to be almost fully compressed.

Is the raised portion on the bottom of the heatsink fitting over the raised portion of the zif socket?

Make sure you followed the as3 instructions from their site correctly. When asked you said you cleaned the surface with alcohol, but it is more than that. They have pictures showing how your surface should look before you apply the heatsink. Is that what yours looks like?

Your heatsink should not come into contact with the die and thermal material until the heatsink is in the exact position where it will be clamped. Be careful to keep the heatsink and pressure applied level when installing. The feet that come with the heatsink are designed to keep the heatsink just above the die until the clamping pressure is applied. This way, the thermal material is compressed in the right way, and not wiped off by sliding the heatsink all over the core when installing.

IMO = In My Opinion

IMHO = In My Humble Opinion

Thermalsistor = Thermistor people! It's spelled THERMISTOR! :mad:

:):beer::D

[linlibj]

The cpu temp on MSI MB is read from diode which is about 10C higher than other readings (thermalsistor??). So 50C is just like 40C for other MB.

[james.miller]

seriously people, you DONT NEED to go to that length with thermal compound. if it was, i wouldnt have been getting 27c idle from an slk-800 with a crappy base on an xp1800+ pally @ 1.8ghz in a pc with ZERO CASE FANS.

Common sence people. I went to no great lengths - i simply made sure there was an even amount that completly covers the core. If you did that, then that ISN'T what's causing the problem.......

[SpliT71]

well i think i found my prob...but i sorta had this idea all along...need some more tornados, btw will a 92mm tornado go on a slk800a?

[modenaf1]

I thought the slk800 fit only 80mm fans?

check your voltage because i had that problem and lowering the voltage helped my temps

[Jeff7477]

yeah.....you can get a 92mm on it. just need to bend the clips a little

[modenaf1]

if you can do that why get a slk900 because the 900 isnt that much larger

[Jeff7477]

the design is a bit different......and its suppose to cool a little better. Personally, I don't like my 900. My next step will be watercooling because air just isn't getting it done for me :(

You need to read this post again. He speaketh the truth. Your getting worked up over nothing

[attitudx]

i own an msi board great board I am using a dual fan coollink ulead hsf, on the msi board at idle i run 47 or 50, but using pc alert click on the cooler xp buttona nd your temps will drop trust me full load i run 30 degrees and that is with folding using 100% of cpu

[ankalar]

yea, try using another temperature reading program

[SpliT71]

mbm5 doesn't support my mobo, so your sayin that what my cpu temp is now, that actually is 10c less then what it reads? at idle now it says 41c, so really it's 31c?

[I.M.O.G.]

Yes spli71 that is what they are saying.

They are saying that those boards are known to read ~10C higher than they should.

I don't know how that is determined, and it could very well be more forum myths, but nevertheless that is what they are saying. Certain boards are said to have readings that are generally much different than other boards.

These types of programs have been discussed here before. By the nature of how they work (this has been explained, but I can't explain it) they only work on a cpu that is at idle. They cannot have any effect on a cpu under load. If you witnessed a difference at all under load, it COULDN'T be from that program.

[emericanchaos]

aside from your motherboard. you're running 1.9v through your processor. that's going to make alot of heat. i wouldn't be surprised if your motherboard was right on. i'm on an slk 800a with a 120mm fan and my temps are about the same at 1.65 volts on a Tbred B.

[cV]

Something's wrong. I have the MCX462+ and by proc is producing TWICE as much heat as that 2200+... insocket thermistor temps never go above 50C.

If those are socket temps then you have a problem buddy.

[SpliT71]

yea they are just temps im getting from the msi pc alert4, should i stick a temperature thing on the core and get a reading from that?
