which Thermal Compound for heat sink on VRAM ?

post #1 of 9
Thread Starter 
Hi guy , i just bought some heat sink for my GPU ,and these for my VRAM , but i realized that i dont know what kind of thermal compound for heat sink on VRAM , it kind of look like silicone ,its not the regular one that i used on the GPU core [Arctic MX 4] .

This is my shopping website :
http://www.memoryexpress.com/Category/ThermalCompund

1) Can I use Arctic MX4 on the Vram ? or just for the GPU core ?
2) If not ,From that website above, can you pick for me one that can be used for heat sink on the VRAM ?

Thank you

the gpu core is the only part that uses thermal paste.
the ram chips typically use a thermal tape, but this is not necessarily true for all video cards

do some searching around the forums/ watch some videos on youtube to do some research before tearing your graphics card apart

I just bought "Arctic Cooling Accelero Hybrid" for my GTX 580 , should I need to install heatsink on my VRAM ?

Normal paste, like MX4 wont keep your HS from sliding off the VRAMs. You need an adhesive TIM or thermal pads.

I think Arctic Cooling make a good one. They supply the stuff with their aftermarket GPU coolers.

I try and find the name of it.

Yes, it all helps. (I have the same cooler) thumb.gif

Wait... you should have the adhesive TIM in the box... its in a small white tube.

Just make sure the HS you just bought actually will fit once the shroud is on. The HS supplied by AC are good and they are the right height.

The memory heatsinks in the picture have thermal tape pre-applied, if the ones you have are the same just have to peel the backing off & stick them on the vram chips.

If yours are just bare aluminum you will want to get some thermal tape, or thermal adhesive (thermal adhesive is permanent though, if you ever want to put the stock HS back on, or watercool with full cover block in the future, avoid thermal adhesive).

+Yes i have the adhesive one in the box , but they are not at the liquid form any more , it turn to the dry solid silicone .

Well, thats not cool. frown.gif

You can mount that cooler without VRAM HS but I wouldnt be overclocking the ram until you can get sinks on them.

The Hybrid fan should supply some ventilation for them. Having say that, you really should mount the HS sooner, rather than later.
