Is your cards stock voltage 1.112? I believe our graphics cards might well be brothers. Mine requires identical voltage at that clock. :eek:

Lol no, i just used that because that's what you used.

My stock voltage is 1.049 @ 925/1375
My everyday OC is 1.169 @1220/1600

The fins will cut off quite easily if you cut them in towards the heatpipes and just take that section away completely, I doubt it will have a detrimental effect as there are plenty of them all along the cooler.

Just snip the top and bend the fins out the way and remove them, that way you could put them back on if needed.

I don't think nail clippers would suffice, but your beastly scissors might snip it, failing that a pair of wire nippers will do the job.



@matt and pete, careful with the vram clocks, that's probably the weakest link to a gfx card and usually the first to pop.



The Gelid should be buffed down/sanded flush with the rest-at the screw point, then it will be a perfect fit on the vrms(that's what tommy would have done given the chance-sniff sniff, pass me a tissue boys, I'm welling up now) and will give even more clearance to the cooler.

That gelid has fair toured the UK come to think of it.:eek:



Matt, £13 dremel nock off right now at your local vivaldis, misc bits tool box £5 that gets you started too.

Crysis 3 is lovely btw, played them all and although the last one was ok looking, this is more to form from Crytek, they upped their game thankfully.:D
Are you saying that if i sand it down (the area when you screw it in) then i don't need to bend any fins? It will just fit? Or that it just creates more space between it and the Accelero heatsink but still needs bending/ cutting/ modding etc.

Ah sounds like you have a high asic card, that would explain your warm temps once you start piling on the voltage. Those low leakage chips (mine included) don't half get hot when the volts come rolling in.

If you sand down the bit where the screws fit, it'll lower the overall height by 1mm and should just about allow it to fit without bending/cutting anything.
It should also let you use thinner thermal tape (1.5mm).

Fwiw, the Enzotech copper heatsinks that Matt used were 14mm tall and just scraped the main heatsink.
The Gelid is 14mm tall before you sand down the end bits. This means it should fit if you get rid of those bits.

My pic here shows it fitted without the end bits removed and look how tall the Enzo sink is when just standing on the bare pcb.

That's excellent news! Thanks for the image and info :D
 
1225 core on the stock cooler. 1340 is the max i can bench at now. 1325 is probably the maximum i can get 24/7 stable. The vrm's would get hot though so to keep them safe 1275 is probably my safest maximum for now. I may well end up fiddling again soon. With the help of tommys dremel i might add one of these to the vrm section.

Niiiiice ;)

Might get one for a bit of a fiddle.

Sorry Tommy missed your post last night. What's vivaldis? Never heard of it but sounds like a poor man's aldi. I'd probably end up cutting off my own arm if i attempted to use a dremel. :D

That's what she said.

It's just the butch bird with the beard called viv at the checkout.:p


Was tired and couldn't be ***** checking if OcUK stocked dremels/rotary tools last night, so changed it a bit in case of competitor rules.

I'd probably end up cutting off my own arm if i attempted to use a dremel. :D

Best way to get on the rotary ladder, it is such a handy tool for general jobs you wouldn't imagine, you sit and think, how the hell am I going too...


Then it hits you, dremel time.:D

Your arm will be fine, it's never going to cut it off, your fingers however...

It can be vicious if you don't concentrate, my brother has had stiches up the back of one of his fingers because of one, and I have been close a few times.:eek:

If you measure the gap and pete marks it off, I can dremel it for you np if it's ok with him, but honestly, your better off doing it yourself-fun times for PC modding.



I do need help though, I spotted this last night:


1 x HIS HD 7950 IceQ BOOST 3072MB GDDR5 PCI-Express Graphics Card (H795QC3G2M) with Crysis 3 & Bioshock PC Games £239.99



I ordered the TF III on Tuesday, but got delivery on Thursday so I could check the offers on Wednesday as I wanted another Ice-Q and I would be able to change it if it popped up on offer, it wasn't on offer on Wednesday morning when I checked the new 'this week only' offers.

I know I said that was me, but after playing about last night, even though the CCC panel oc was applied, BF3 gpu usage through the Ice-Q AB graph thingamyjig was reporting low/high gpu usage with the core spiking constantly, ramping up and down all the way through.


After using His iTurbo to apply the same clocks, gpu usage stayed constant, so back to square one using 2 different oc tools.:(

So I'm guessing it must be something to do with the boost bios not playing ball with CCC oc'ing.

What's a bloke to do?

DSR the MSI and go Ice-Q, in order to set the clocks and forget(ah bliss) or persevere?

I can see an Ice-Q getting bought this morning for Monday delivery.
 
Go with the Ice-Q tommy.

Oy yoy yoy.:eek:

Can't believe I just did that, oh well, if the cooler is as good as the other one(silent in my rig on the desktop), since I'm not after maximum clocks, the AC might have no where to go.:eek:

If that's so, look out lads for my modified AC Extreme/chunky Alpenfohn vrm heat tamer in the mm going up for grabs along with the rest of the Alpenfohn heatsinks-won't be sold off cheap just to get rid however, their both hard to get most of the time, not to mention the mod took precision skill to achieve.;) :p

I'm not going to add to the cost price or anything, it just won't be much cheaper than new-Moogley got almost full purchase price for his used stock AC, failing that, it will be kept for the next round of gpu's.:)

Tommy ill take the Meaty Peter huge vrm sink off you. Name the price. ;)

If i can just fit it easily with glue without modding then i want it.
 
You not been to bed yet bud or is just the fiddling urge clouding you thoughts?:p

The AC needs the modded fin cut out job for the well hung petey vrm sink to fit.:)

If I do say so myself, I imagine tim will suffice as the job was that precise(aye right, called pure luck tommy), the AC heatsink fins hold it firmly in place anyway.

I call it fiddlers brain. Thanks for reminding me. :o
 
:cool:

Tommy has maybe made a disturbing discovery when I was checking availability of the AC+Alpehnfon heatsinks here at OcUK(just in case I punt mine).

How come when they are both in stock the AC is normally £69.99 and the heatsinks cost £13.99, whereas both are showing out of stock@£49.99 and £11.99?

What's going on OcUK?

On a happier note, tommy's Ice-Q has shipped and on route for Monday.:D

Regarding the huge Peter vrm cooler, did you use thermal tape either side of it like the Accelero instructions say and how tight a fit is it in between the black blocks the one side and the small chips the other side is there any risk of shorting? Also is this the same one Overclockers sell?

Yes, all taped up both sides of the vrm-absolutely essential if you don't want to short the card with any vrm sinks.

Absoluetly perfect fit:

If you want to use the beast-aka big alpenfohn vrm heatsink, you need to dremel the AC heatsink so that it fits:

Yes, the very one:

1 x Alpenföhn Passive DRAM / VRAM Chip Coolers £11.99


 
My card has been successfully RMA'd so now all I need to do is try to get the faulty accelero replaced. Failing that I'll either need a second hand accelero or to try and get a replacement fan unit. Fun times, I can see me having to buy another. :(
