No lower / maybe even higher temps after thermal paste

Core temp shows 48-50*C idle..

This is really annoying me now seeing as my temps were better before i applied the paste. I put a thin layer of paste on the CPU, put the heatsink back on, checked and rechecked it was seated properly, what have i done wrong!?

Oh btw.. PC WIzard and BIOS used to show Core 1 and 2 as 50*C, but there was another temperature called just Processor temperature. That used to go from -10*C to 112*C and ridiculous things like that in seconds (clearly wasnt working)

But.. that temperature after putting new paste on goes from 31*C idle to 36*C max load.
 
Did you also make a dab of TP on the CPU? Sometimes, too thin a layer won't do anything. the TP needs to contact the HSF fully in order to transfer heat away from the CPU. If you're just going to apply it one way, do it the dab way.
 
It probably just needs cure time. Also, ambient room temp will affect the inside-temps, too. I'd say give it a week or two and see how it looks.
 
hey imsati, could you please explain your method again in more detail?

I'm going to re-apply the TP and everything before I start OC'ing and I want to make sure everything is in mint condition.

How much TP should be used for the thin layer approximately? For the dab? To clean it off 70% isowhatever alcohol is acceptable, right? And how in the world do I spread the thin layer anyway?

And also, I'm not sure if you do this, but do you apply your own TP to your GFX card as well?

Sorry for the questions, but thanks! :D
 
sorry if its said before, but thermal paste that just has been applied needs to set itself too. so, you would notice a bit higher temperatures at the start, but those will drop a few degrees when its setting.

Certainly.

First, getting the old stuff off...
Start by removing the CPU from the MoBo. Carefully scrape off as much TP as you can with a credit card or razor blade from both the CPU and HSF. Next, take a lint-free cloth (coffee filters work GREAT) and rub away any residue. Keep rubbing away until no more greyish-material is picked up by the filter/cloth. Now, take rubbing alcohol (higher-purity stuff works, too, but rubbing alcohol is fine if you already have it and don't want to buy the other stuff). Put a few drops of it on the filter/cloth and again, keep rubbing until no greyish-residue can be seen. Do this for both the CPU and HSF.

Now to apply...
As mentioned before, I have OCD to begin with and I am overly-obsessed with certain things, TP being one of them, oddly enough:confused: so I've stressed out about finding that 'perfect' application for a long time. First, take a good-quality TP, such as AS-5. Place a small amount on the CPU and carefully spread it over the entire heat-shield (on the CPU, not the actual heatsink/fan). The goal here is to make an even, thin layer, and the end result is no striations/lines. ((You're done when you think you can barely see the heat-shield, but it might just be your eyes playing a trick - does that make sense?)) My wife watched me spend 5 minutes one time making it perfect, so take your time with it. Now, re-seat the CPU in the Socket and lock it into place. Once it's in there, carefully put a BB-sized dab of additional TP in the center of the CPU. Gently place the HSF over it and lock it into place very carefully. The pressure from it being locked will spread the BB-sized dab you placed evenly over the core of the CPU's heat-shield.

And that's it! I've tried the thin-layer only method, the line-down-the-center method, the BB-sized dab only method, and every other possible combination. I let each method cure for a while and checked temps periodically. In the end, this method offered the best results, as shown with my D 940 (typically an oven) running at a very nice 31-32*C at Idle and barely reaching 43-44*C under load with a room-temp of 72*F. Pretty damn great for a D-series!

alright, cool thanks a lot

just used that method today and as soon as I fired my computer up, the CPU Temp on PCWizard went down maybe 2-3 degrees. But interestingly, I think my cores were running maybe a degree hotter and I noticed that my computer wouldn't fail Prime95 on the previous OC so I had to bring it down to stock settings. I figure that I should wait for the cure time

I'm running a E2180 and my idle CPU temp on PCWizard seems to be 30 degrees, and core temps give or take 10 degrees hotter than that, atm, which was roughly what was the temps before (but of course that was with the cure time and all) so I'm thinking that this will definitely bring lower temps than what I had previously

EDIT: this is idle temps btw, load temps for the cores hover around 55 degrees, also before, I had the side panel opened which probably might have helped temps? Ambient is pretty cool

how much lower will the temps go as I give it time? I'm starting to think maybe it's running a little too hot in general, as I'm using MX-2 paste and a Zalman 9700..

sorry if I'm thread hijacking! But I thought I'd rather post here than just create a new thread about the asme thing

me?

The OP was using an E4400

I'm using an E2180

I tried turning up the processor fan 100% by turning off Smart Fan in BIOS and it made no diff in temps.. :confused:
 
Oh, sorry.. i didn't even see your post :P


Do you have the zalman so that it blows the warm air out of the case? That does seem a little warm for a zalma 9700, its possible that the programs are reporting the temps wrong. However, 55c load still isn't bad. I would have thought it would be a little cooler. But its not hot, i wouldn't worry about it..

Heres how i apply the paste for a dual core. Single core, i use the "dot" method. With dual core, i use the line method, and it must go in the correct direction.

But the method you use to apply it should have no more than a 4c temp difference..

btw, im using the mx-2 paste also with my e8400. I would tell you what the temps are, but i can't say for sure. These E8xxx series are reporting fishy temps
 
hehe no worries! hmmm yeah, the first time I applied the paste I used the line straight down the middle method, and this time I used imsati's method

There seems to be a minimal difference in temperatures, but either way I'm not satisfied with my temps as this is at stock..and the HSF and TP are pretty top notch

Yeah I have it so it's blowing out (so the actual fan itself is facing towards the front of the case) and the air is actually quite cool

Bleh, I don't know. I see guys reporting there E2180s OC'ed at 3.0ghz and their idle temps are like 25-30C..Not sure if there using Speedfan or not though

I guess I should just wait for the cure time. I only did apply it about an hour ago :D Then again, maybe I used too much! I did just a little less than you would normally apply on the line method, spread it out, and then the BB in the middle..

I'm not even sure if MX2 has a "cure" time like AS5.. it is better than AS5 though :D

Don't feel bad, i don't even know what my temps are for sure :mad:
 
kevlee, glad it's working for you:) Your temps will come down over the next few days/weeks depending on how much you use your system. When I first applied with that method, my D 940 saw a 40*C Idle temp. over the next 3-4 days it dropped to 34-37*C, and then maybe a week after that evened out to 31-32*C

You're seeing some nice temps already from the start, so I think you'll be happy with the end result:)
