The point of watercooling is make the most effective cooling while also trying to make the rig quiter...How is using a giant fan blowing directly on the vrms with the crappiest/tiniest little heatsinks going to be more effective or quiter than a full coverage block.
Universal blocks are okay but generally aren't the way to go.

Tell me where i can find a full block @ $60 for a 7970 card

How much is it for the heatsinks you'll need to go with it? XSPC full cover blocks are right at the $100 price point. If it costs $20 for heatsinks, and 60 for a "universal" block you're at $80. You've saved $20 to get worse overall temperatures for the GPU (higher temp VRMs/memory modules). Just saying..

The XSPC block has got to be the worst "full" cover block around. There is a reason it is cheap. The XSPC block is more like a gpu and RAM block since the actual block only makes contact with ram and gpu with water fow while the VRMs don't have contact with the copper block or any water flow.

XSPC is not a good example of a well designed full cover block.

Also many of the better over clocking HD79XX cards already have a heat sink on the VRMs that work well.

These are the stock heat sinks that come with my card.

BareB.jpg Very good design IMO. I want better though.

He probably bought a used block. Nothing wrong with that. Anyways, if you can't afford 30/40 bucks difference for a fullcover, sheesh. Key word is can't, now if you won't that's a different topic altogether.

Obviously it's no better than stock if you're hitting 110c lol.

Keep in mind that my card is over clocked to 1200mhz and the Sapphire HD7950 950mhz edition does have the most powerful vrm design of any current HD7950s so the heat is more than likely going to be higher than other HD7950s.


I've read the temps on the VRM are rate to like 150C. My dedicated water block on the VRM should help lower the temps.

All you are is a bag full of excuses. It's hot, it's freaking hot. Who the hell said 150c is safe?? More vrms equals cooler not hotter!

Chill out.

My card runs fast and stable. The stock vrm heat sink seems to help keep the card stable.

You obviously are not interested in this water block.

I posted screen shots of my VRM temps because I want everyone to see how hot the VRM gets. I know it is hot. I don't like to run any of my hardware to its max rated temps.

Just because you prefer a full block for HD79XX cards doesn't mean everyone else also prefers full cover block.

I prefer dual block. Works great. I will post the results from my dual block configuration once I get it set up.

Hang on bro... you wouldn't actually let your VRM's get anywhere near that, would you?

Dude! You realize whatever gain you were hoping to achieve by going gpu only is killed by throwing in a vrm block right? It's not magic you know, about gpu only blocks. They cool better than fullcovers because they are NOT COOLING 110C VRMS along with the gpu! What do you think happens when you throw a hyper restrictive vrm block in the mix? doh.gif

No. I ran a 10 minute Furmark test just to see how hot the card got with stock cooling and the VRM temps reached 110C.


I just did a google search for the VRM part number 10073 R15 on my card. This is what I foud:
http://www1.cooperbussmann.com/pdf/79793630-1b1e-49f8-a6d0-ea9b2be9f2e4.pdf

My VRMS.


VRMSapphireHD7950950mhz.jpg

Rated for up to 125C operation. Looks like my OC is pushing the VRM temperature limits.
