SVC GC68 clip question. Also, we should start demanding 3 lug clips :)

I'm a little annoyed by the GC68 clip design in general. For anyone that hasn't seen one, the cooling fin base is rounded on the GC68, unlike other coolers I've used, so that the thickness in the center of the cooler is wider than at the sides (see picture at svc). However, the slot for the clip (which runs perpendicular to the fin rows), is cut parallel with the base so that it goes through the mound. Now here's where my annoyance lies: the clip that comes with the cooler is a normal 1 lug clip, with two nubs at the pressure axis to keep the clip/heatsink from sliding -- the nubs go between two fins. The nubs, however, are very small, so small that if you just turn the clip slightly, one nub can fall down into the clip channel below the top of the mound and cause the clip to be crooked. Once you get the hsf mounted, the clip is just barely holding at the top of the mound, ready to slip into the channel. What's the deal with this? I've found that the clip is extremely tight when resting at the top of the mound, so this makes me think that it was intended to drop to the bottom of the channel, but then the nubs get in the way. If you were to grind off the nubs, the heatsink/clip could slide back and forth. The other alternative is to slightly drill out the mound where the nubs go so that they can fall to the bottom and remail inbetween the fins.

So, does anyone have a genuine explanation of how it's supposed to work/what the manufacturer's intentions were with this POS clipping mech?

Furthermore, I'm pretty tired of one lug clips. As a community I think we should start demanding 3 lug clips. Geez, is it really that much harder & expensive? I don't think so. My volcano5 has a better clipping mech. than these newer coolers...

Agreed; I recently had to install an XP with the retail heatsink; that clip was so stiff and tight that I took it out and bent it a bit straighter. That thing was insanely rigid - only uses the 1 lug per side; nice'n'easy to snap the thing off. The 3 lugs are goood.
 
no comments on the gc68? 🙂😉🙁😱:disgust:😀:|:Q😛😎:frown:😕

I installed a GC68 for the very first time this week (my first heatsink install ever) and it was a piece of cake + it dropped my temps 7C. No complaints here
 
I installed one this week as well, onto a new Athlon XP 1800+. Keeps it nice and cool too! I ordered a couple of these from SVC, as I have had nothing but good experiences with them so far.

I really like this heatsink, but you are right about the clip. I have 2 of them running in Athlons XP 1700+ and 1800+. In both cases, I thought the clip was extremely rigid, so I bent it a little. In the first installation I bent it the right amount, as it installed with a reasonable amount of force applied. The second i overbent it, so it didn't hold in place.... I had to fix it.

Aside the clip, I have nothing but praise for these little pieces of metal. They work much more efficiently than the retail heatsink, and beat the volcano 6Cu by 5 degrees, not to mention that they are much more quiet.

If you don;t mind shimming the CPUs, I think that is the way to go. By the way, the shims sold by SVc and webuildpcs.com are the best, they are copper but they have flanges to keep them in place by the CPU ceramic, they fit nicely over the cPu and they don't move.
 
i just got one to replace my volcano 6cu,

the SVC had a bit tougher installation (rigid clip), but I shaved a few degrees off, and its much quieter than the volcano 6.

I only wish I got this heatsink sooner, and didnt waste the money on the volcano..

tip: if you're afraid of slippage, put 2-3 layers of masking tape under the lug incase of a screwdriver slip, I dont know how much protection it will offer, but its better than nothing.

this heatsink would be perfect if there was an additional 2-3mm copper attached to thebottom of this sink, and a 3 lug clip that wasnt so stiff.

Mine came in last week. Its great.

I was tired of listening to my delta sitting on a thermosonic thermoengine. I had to pull the motherbooard out of the case to remove my old HSF (screwdriver wouldnt fit to give proper leverage). I think I chipped the edges of the cpu processor in the process.

The GC68 went in pretty easy. Plus with its clip design, I wont have to pull out my entire MB to take off the HSF. The clip was pretty stiff, but I used a big screwdriver to lock it in easily.

I tried a couple different fans with it: Crystal Blue LED thermal, Panaflo, and the one it came with. I'm using the Crystal ran right now, because it has the highest cfm potential and just looks cool : ) The temps are higher then my last HSF, but there's no more jet engine noise in my case.

It was well worth the money. I agree with frastini. If I only I had found this first...it would've saved me $$$, sleep, and a few headaches from the noise.

What kind of temps are you getting on your 1800+ with this cooler now? I am running CPUidle Pro on my system and my jaw hit the floor when I went from a Thunderbird 1.2Ghz (which averaged about 102 F when it was idle) to an XP 1800+ with this cooler and the SVC heatsink. My idle temps now are 85 F or if I disable my Palm hotsync software, 78 F!!! :Q I didn't change anything else in my system, and didn't touch the sensor thermistor under the socket when I put the new proc in.

The idel temp is 39 C for the 1800+ going to 46 at full load (demos of serious sam). the temp in the 1700 is 40 C at idle and 49 at full load. I have NO case fans, and the case of the 1800 has better ventilation.
 
Is this HSF loud? I am looking to get a new HSF for a celeron system, and a duron system as well. My temps are okay right now, but the HSF are loud, so I am looking to get some quiet HSF.
 
I have the GC68 and I noticed that the clip can be put on backwards. Yes, it's stiff so I bent mine like most everyone else. Look at the clip and you will notice that one side is longer. The longer side goes towards the side of the HS that has the notch cut out on the bottom. Maybe this is quit obvious to everyone else; however, I did put the clip on backwards and it didn't sit flat on the die. Glad I didn't chip that sucker...those 933s are still above $100.
 
this heatsink/fan combo seems very quiet comparing to my old volcano 6cu.

I have the heatsink, and 3 panaflo l1a's I do hear the hum of the fans..
but its not bad at all.

If you are planning on using this heatsink on a celeron or duron, you may want to replace the fan with a panaflo l1a,
it will quiet it down, and still provide plenty of airflow. The stock fan is pretty quiet..
