I need to consider cooling as problems have arisen

[Flyingbig]

First off i own the following case,

http://www.overclockers.co.uk/acatalog/Sunbeam_cases.html

I recently upgraded my case and grpahics card and i have experienced a few crashes that i blame on my graphics card overheating. My XFX 7800 GTX is overlcoked to 490/1300 out of the box and it is idling at 53 degrees and going well over 70 degrees during full load and on top of crashing out a few times of games (complete freeze out) i can see wee white sparkles (just wee glimpses now and then) that are a side effect of my card overheating as i seen loads of them when i tried a massive overclock so basically i need help in deciding which steps to take now to better cool my case. Now i am currently unsure about putting a Zalman on my 7800gtx as i believe i need extra ram sinks which is fair enough but i need confirmation that this worls 100% before i buy. Also is there any other measures i can take to cool my PC, i currently have one fan on the side of the case and one at the back of the case and thats it and they are small fans not the large ones as i can't acomodate them in this case due to lack of space.

For the price of a PCI Cooler i could buy a Zalman, which would be more effective?

You really think so. There are other types of VGA blowers that are not so expensive and do a very good job.

Antec Slot VGA Cooler

ZALMAN ZM-GWB1 VGA COOLER

Artifacts are not always the result of overheating gpu's. Not getting enough voltage is another frequent but missed cause. Your gpu temps are a little on the high side, but nothing to worry about. Your card should not be "freezing" because of those temps at all. What kind of psu you running? Sounds to me like maybe the 7800 isn't getting enough voltage for its OTB oc. Ramsinks do very little....gddr 3 runs quite cool anyways...The Zalman VF700 series would be a much better purchase than a slot cooler imo...do you have the option of installing a front intake w/ that case? Look into some med/high speed panaflos (@ svc or jabtech) to improve your case airflow. Also wire management plays a vital role in airflow....make sure wires are tidy, out of the direct path of airflow, and preferably rounded ones.

No room for front intake, i really want a Zalman VF700 but i need someone to confirm that it is fully compatiable with 7800gtx series of graphics card. I have a Tagen PSU so plenty of power but i will check what voltage i have it set to for my Graphics card and report back.

 

[JEDIYoda]

yes it is compatable!!

 

[Flyingbig]

How do you know? Do i need extra ram sinks? I need a little bit more than just you saying its compatible.

 

[JEDIYoda]

read this forum....do some research....
its compatable.....people have posted in other threads.....
also it comes with 8 ram sinks.....

If I see one more BUMP from marvw! :laugh: :laugh: Now stop it!

JBDan i was in the bios looking to up the voltage to my crad but i could onlu seen ram/cpu voltage and various outher options with no idea what they were. Which one refers to the graphics card so i can up the voltage? Many Thanks.

I would consider investing in a case that is designed more for performance than looks, if you're doing such heavy OCing, too.

Maybe you should turn oc'ing off, that should be a first. And I think XFX often has heat problems, my 6600GT also runs hot.

Then, I'd get one of those clamshell coolers, and add a few fans onto the case. Or get a cheap case that has multple fan options.

Its overclocked by default guys, i haven't overclocked it one inch.

You can increase the pci-express frequency of your card (atleast on most newer mobo's)*EDIT its in your BIOS *end EDIT . Many have found this to help with stability issues with their cards. I'm still on AGP so I am going on what I read and what I see. Toy with it some and see if it helps your "freezing" issues. Raise it 10 MHz at a time and test thoroughly with the games that make it "freeze" till you find a sweet spot...if you do lol. pci-e specs are at 150W now per pci-ex16 card if I'm not mistaken. I think before the PCI-SIG 1.0 spec for x16 cards, it use to be 75W... So you do need a beefy 12V rail on your psu for the 7800gtx imo. Like I said play around with the frequency some and see if that helps. I really dont think your temps are the cause of this unless they are very inaccurate.
