No lower / maybe even higher temps after thermal paste

I cleaned off the thermal PAD that was on my heatsink and CPU (known to be bad) and put some Arctic Silver Ceramique paste on.

I made a cross on the heatsink (says a line but i dont know which way im supposed to make the line so i did a cross)

I then put very small amounts in each corner, spreaded best i could with a credit card but it's not very well done.

I'm getting just over what i was getting with the pads now (Just applied paste though)

Do i need to wait for it to take affect or anything? Bit annoyed that it hasn't changed anything.

Btw my idle temps were usually 47*C for both cores, which is now 49*C/50...

Update: Hmm strange.. On my temperature reader (PC Wizard 2008)
it has:
Core #1: 49*C - 50*C
Core#2: 49*C - 50*C
CPU Temp: 31*C - 31.5*C

So i'm a bit confused :\

Also, when i got the paste its form was a bit different to what i was expecting. I was expecting it to be less dry. It was hard to work with and move and there is quite a bit of paste just stuck to the side. I don't know if this is typical or if its dried out and thats what causing it or what.

Applying TP is a sensitive procedure. While most do take time to cure and that could be why you're seeing higher temps, it's possible you used too much. Too much paste = why bother using any at all.

Just to be safe, I would remove the HSF , clean that and the CPU off, and start over.

Place a bit of TP on the CPU and spread very thinly with a credit card. Take your time, be a pain in the ass with it, make sure it's perfect; if you have OCD, make this one of those things you quirk over (like me!). After that, seat the CPU in the Socket and lock it into place. Then put a BB-sized dab of TP in the center of the CPU and gently put the HSF on top. Very carefully (so you disturb the HSF as little as possible) lock the HSF into place, then boot up and check temps.
 
Sounds like you put way too much on. All you need is a small dot in the center a bit larger then a grain of rice, just to fill in the air gaps (it will spread out with the pressure between the CPU and HSF). Too much is just as bad as too little.
 
Speedfan is showing:
CPU: 35*C
Core 0: 39*C
Core 1: 39*C

This seems more likely and id be very happy if these are coorect, anyone know?
 
Well, they're lower, but not what that CPU should run. Read Posts 3 and 4, then check it again after.

You're saying, spread some over and then apply a small dot in the middle?
 
I found that works best for me, yes. I tried *every* way imaginable a while back, then gave each way a few days to cure a bit. The thin layer/dab combo yielded the best results. I'm also very OCD with certain things, this being one of them I found out in the middle of doing it, so I paid super attention to detail.

Doing it that way keeps my D 940 at a relatively cool 32*C at Idle and 44*C at load. Pretty damned good for a D-series!
 
PC Wizard is showing exact same temps.

Speedfan has the cores at 37*C, which i heard is pretty good for Core 2's, they run pretty hot anyway. But im not sure which is reading the temperature right.
Can anyone think of any other programs i can test with?

I did a very thin layer all over the CPU after cleaning off the other stuff well.
Did a much better job this time. I think 37*C is fine aslong as it is the actual temperature, so i need more program suggestions ;)
 
Better temps, but I don't believe my Pentium D runs cooler than a C2D. Would be nice, but...no.

Have a look at the CPU temp through BIOS. That will give you the most accurate number. Just enter BIOS, go to the Hardware Monitoring screen, and let it sit for a few minutes.
 
Nah, the BIOS isn't very accurate for me... try Core Temp, that's what I find to be the best, it uses the actual sensor inside the die of the CPU!

Ah right, That's cool, Jay!
I normally just put a thin line down the middle, I've also tried spreading it, but it didn't work well at all for me :(
 
When in BIOS, your CPU will not scale down via EIST. Therefore, the temp it shows will be at full speed, though not under load.

BTW, Korn, I noticed your myspace thing the other day and added you on.
 
if you look on the website for arctic silver, maybe try looking at the directions for their 5 version rather than the ceramique (i never have looked at that one). anyway, it's pretty self-explanatory, and shows you where on the cpu to put the stuff.

applying it in an X pattern is wrong and probably going to not help matters at all. it's really not that difficult to do with the right instructions.
 
I did a superPI test (uses CPU to work out sums or something, uses cpu power anyway)

On Speedfan the cores went from around 39*C each to 51*C max, which seems like decent temperatures.

But on PC Wizard it displayed as up to 65*C-67*C

Before with PC wizard i was 43*C idle, 55*C max. How could it have gone up from me removing the thermal pad gunk that was on there and putting professional paste on evenly and thinly..
 
Most TPs will need a cure-time before they are working to full capacity. Also, different Temp programs will give different results. You have a C2D, so you may have better readings by using Core Temp.
