Has anyone modded this heatsink so it fits into a screw setup and not a clip setup?

any links on how to mod it would be nice

also my mobo uses a 4pin connector for the cpu fan

this heatsink uses a 3pin

can i just plug the 3pin on my mobo or do i have to buy a converter or something?
 
The 3 pin will plug into the 4 pin fine motherboard fan hearder fine.

Have a look for the Thermalright socket 775 bolt-through kit, that should do the trick.
 
That's just an error in the description on OcUK, it's really a 4-wire fan. However, the three-pin connector fits the four-pin plug anyway. If you look at the mobo connector you'll see the locating tab is offset by one pin to allow this.
 
if i get teh thermalright bolt kit don't i have to dismount my mobo and install on from the back?

i've been hearing rumors that one can twist off the push pins and use regular screws to screw on the heatsink
 
Yes to install bolt through kit involves taking the motherboard off to fit backplate. But tbh if it ain't broke don't fix it.

I've fitted mine with bolt through kit (albeit not thermalright) and the temp went UP by a few degrees. Since then I've even lapped both cpu and heatsink and the temp still wasn't as good as it was.
 
well...

if i don't fix my cpu temps

i really can't play games

after 15 or so min of playing any game the temp skyrockets to 70C and at that point my cpu fan + case fan go to 2000rpm

is it easy to take off the push pins?

btw i've found another 530 user that has dones this mod and seems like he used the pins below to attach eht heatsink to the mobo

is this safe in your opinion?

The 'rumor' is more likely to be from someone useing bolts, nuts, springs and washers (paper/plastic/rubber) and it's been retold as 'screws'
M4 bolts/nuts etc can be had was a quality hardware store for pennies.

You don't 'need' a back plate - but bolts will bend the mobo more that push pins, so a back plate will remove the risk of damage.

You can invent the mounting (simular to how waterblocks are fixed) with the bolt head at the back - this way swapping coolers/block doesn't need the mobo removed.

Did you use a cheap TIM or AS5.
The freezer has MX-2 on them with is one of the best anyway - if you used AS5, the it's has a burn in time (200h I think) in which temps will drop 3-5c
Cheap TIM is well cheap.
Also if your ISH is not level it's very easy to not apply an even presure with a bolt fixing.

Edit2:
removing the push pins is easy with a junior hacksaw / tin snips / shape knife.
But I'd not use those case screws.

If you don't like 70c+ get a tower cooler or drop the OC

well think rumor isn't really a rumor and someone has actually has done this and uploaded pic

im just wondering will the mobo actually bend and crack?

the problem with the thermalright bolt thru kit is i can't really find it for purchase around my area

here are the rest of the pics

the picutres show how it was done with store bought screws and hex nuts but the author later mentions the cd/dvd drive screws work fine as well

AS5 before and MX-2 after bolt through kit. Now thinking about it I've not tried AS5 again as I just assumed MX-2 is better according to all the reviews.
 
That's an M3 bolt head in those photo's - not a case screw.
And yes that should work - still need to remove the mobo as there is a square rubber washer and bolts on the reverse side.

Tower cooler - TRUE, Noctua NH-U12P, Thor's Hammer, Megahalems, Mugen 2 etc there's lots, and they look like towers block rising from the mobo.

@steve258 - that's very unusual - something must have got miss alined with the new mounting :(
Might be TOO tight - if the bolt kit has springs - have you tried losening/tighening the fixing to see of temps change?
If the kit doesn't - get some they really help.
Also did you change anything else at the time - cable routing/case fans/add pci card?

Well, since optical drive screws are M3 anyway, yes that would work

You still need at the minimum 4 nuts and 4 washers. M4 is recommended as it fits the hole better, what with it being a 4mm diamater hole...

Without backplate is fine if you don't overtorque it, and still better than push pins. I like the ek mounting hardware, so tend to use one of their backplates with M4 bolts
 
question
why does i need washer and nuts?

i am attaching the heatsink to a inspiron 530 mobo

i believe the cd/dvd screws will fit w/o any nuts or washers

do i need the nuts because the screw is too long?
 
If you have no washers, what are you hoping the screws will bit into? They need a thread to connect to, so either you tap the mounting holes in your motherboard or you use nuts. At a cost of about 2p each there's no excuse not to. If you tap the motherboard I want photos

If you don't use non-conductive washers you are likely to damage the board and cause electrical shorts. This would be retarded of you

no airflow in an inspiron 530...

only have case fan sucking air out from the back

i found this while searching the net

do i have to buy or make a backplate like this guy?

If you have no airflow in your case then doing this will improve nothing.

You need nuts and non-conductive washers so that you don't short out/damage/blow up your mobo!! A backplate is advisable as there will be more pressure exerted on the board. Still comes back to the point that if you have no airflow in the case that this will achieve nothing.
