Hi,

I have a Dell Computer:-

Win XP
Pentium 4 3.6 HT
1 Gig DDR
Geoforce 7800 GTOC.

Basically i have just fitted a new Artic 600W power supply, as you may know Dell make it impossibe to upgrade components.

I had to unscrew a plastic cover which had the Heat Sync on (without realising) and i lifted it out and then noticed it was covering the Chip.

Now there is paste on it and on the thing i took off.

Will i need to apply new paste?

Bare in mind this pc is about 3 months old.

Any help advice appreciated.

Thanks

Michael

Thermal paste should be applied as thinly as you can and it could be said that if you can see it, there is too much there.

I would doubt very much that you need to apply more but do make absolutely certain that the heat sink is fitted correctly and as tightly as possible when you put it back.

Thanks £dstowe.

Much appreciated mate.

You can vaguely see it, its Grey and spread fairly thinly across the chip

Will your warranty have been affected by the PSU swap?

Don't want to interfere with negative feedback but i always thought that you must clean off and reapply thermal paste or heatsink pads every time you move or replace the heatsink. Also as stuartli suggests the warranaty would almost certainly be affected.

It is important to clean off thermal pads completely as they are no longer flat after they have been disturbed. Regarding paste, yes, it is better to clean it off in case there is any particulate matter that has attached itself to either of the mating surfaces whilst the two have been separated. If care is taken and all dust avoided/removed then this can be dispensed with.

Thanks for the replies.

Just a bit worried now from what most of you are saying.

So i need to apply a new paste to the processor chip?

Seems a bit confusing the link but thanks.

Yeah will void the warranty but i needed a new power supply.

Don't apply paste to anywhere that there wasn't paste before.

It is a case of "less is more". Don't load up any surface with the paste. The small metal square in the centre of the CPU is the part that needs the paste, not anywhere else on its surface.

If the machine is only 3 months old, and the power pack has failed (Why else would you change it?), it suggests there is something wrong with the system, and it should have been sent back to DELL.

Terry.

There is nothing wrong with my system.

The powers supply that came with it is 375W and i needed a higher power supply for my graphic card.

The reason this all came about was because a cord from the power supply was convieniantly placed under this plastic box where the heat sync is.
